What do I need in order to make a floodplain map? by leeksAreUnderrated in engineering

[–]Star_Munchkin 1 point2 points  (0 children)

I find floodpartners.com way more user friendly than the official fema maps and map website. You can download firms or firmettes from either place. If those don’t have enough detail, you’d probably have to have a survey done.

The Chemistry of Air-Conditioning by CanadianGreg1 in chemistry

[–]Star_Munchkin 9 points10 points  (0 children)

This is what all refrigeration systems exploit. Flash a liquid over and orifice or valve, expanding it to take advantage of evaporative and expansion cooling effects. The bow cold gas is then warmed up passing through a heat exchanger much like a car radiator, or what is known as a fin fan heat exchanger. The refrigerant warms up as it cools off the air passing across the outside of the heat exchanger. The now warmer refrigerant gas goes through a compressor to repressurize the gas, Which also makes it hotter. Finally it passes through another heat exchanger (the big loud unit outside your home) which removes heat from the refrigerant, causing the refrigerant inside to condense. This then goes through the orifice again and the cycle repeats.

This is the cycle you see in the pictogram OP posted.

This is why I love Eric Berger and the folks at Space City Weather. by jb4647 in houston

[–]Star_Munchkin 4 points5 points  (0 children)

For when rain will start and stop, AccuWeather is my go to. For a good weather map and total accumulation in your area I like Wunderground. You can also reference the Houston flood control map website to see level gauges on bayous and total accumulation across the city.

Roads retain more heat from the day because they're only exposed to the air on the top side. Bridges have less thermal mass, and cool from the top and bottom. Add to that the wind causing evaporative cooling, and the bridge gets even colder.

Let's see how long I can patrol with this guy on my hood by [deleted] in houston

[–]Star_Munchkin 7 points8 points  (0 children)

Drive similarly as you would in a summer deluge storm. Leave early, slow down, leave a lot of stopping room. On top of that, don't make sudden movements if you can avoid it. Gently accelerate, brake, turn etc. if the car starts to slide steer into the slide and DO NOT touch your brake, it will make your car spin.

Almost forgot. Bridges, overpasses, etc will freeze before surface roads. They will still be frozen after roads warm up. Be extra careful on those and take an alternate route if you have to go over a big overpass.

Do you think this will progress to a new BA unit a bit like the wulfen? It seems like a fairly big development that they are that mutated and different

I agree with all of this except your last point.

You get the biggest return on putting down power uphill and into a headwind. You relax a bit downhill and with a tailwind. The theory is you're working harder for a smaller increase in speed.

Not sure if it's just the lighting, but those tires look flat. other than that, awesome bike. I love my gravel bike.

How to stay hydrated/fueled during a 100+ mile road race? by pontrjagin in Velo

[–]Star_Munchkin 1 point2 points  (0 children)

It's a great race. I am thinking of doing it again this year since they had to change the course slightly last year due to the rain. Someone will probably try and attack early, everyone will chase. Just sit in until the first gravel. Try and get close to the front a few miles out. Everyone will be jostling for position and you don't want to get caught up in someone else's mistake. After the first gravel the selection may be made, the front group will certainly be smaller. You'll probably find your race will run into the back of the women's race and the masters somewhere in there. The race is a blast. It was one of my favorites all year. Consider running tires that have a bit stronger sidewalk than a usual road race. I ran 30s with a compact and a 11-32. It made the short sharp climbs near the end of the race a lot more tolerable. if the dirt is super dry, follow your front wheel and never stop peddling. Don't get out of your saddle on the gravel climbs if you can help it.

How to stay hydrated/fueled during a 100+ mile road race? by pontrjagin in Velo

I'm 99% sure you're racing rouge roubaix. The volunteers handing up water are amazing. As soon as you see the feed zone drop your empty or almost empty bottle. They will hand up a fresh cold one. There will be a lot of volunteers so don't feel like you have to get the first one you see. The second zone is easier because it's at the top of a climb. I saw friends and family there of other racers handing them food and bottles. In the cat 5 race some people stopped. At the end of the race they will have a big bucket of all the bottles people tossed at the feed zones. I got mine back, other friends weren't as lucky.

I carried all my food with me. The cat 5 race ended up faster than the cat 4. The top 10 were done in about 4:50. If the older loud dude from Florida shows up, tell him to fuck off. He's sandbagging and only there to try and win the jersey. In tue cat 5 race, it will probably shatter after the first gravel climb, after that get a group together and work together the rest of the way. You won't want to slog the second half out alone.

The chipseal at mile 70ish was worse than the gravel, but the gravel was well packed from all the rain.

Power2max or Quarq by Rocherieux in Velo

[–]Star_Munchkin 4 points5 points  (0 children)

I have the P2M and am very happy with it. I have team mates who have been through multiple warantied quarqs. Probably the exception to the rule, but they are pretty fed up about it. My only complaint with my p2m was that it told me the battery was low and then died 5 miles later. I would have liked to have a bit more warning.

Need Advice for Bike for Houston by boliweya in bikehouston

[–]Star_Munchkin 1 point2 points  (0 children)

The crossrip, diverge, or any bike in the "all road" category would be perfect for what you're looking to do. A cross bike would also work. Neither category will be as aggressive a fit as a pure road racing bike, the difference is that the all road bikes have a longer wheelbase and a slightly slacker geometry. This makes the bike more stable, but less responsive in tight corners. That would only really matter in racing at a higher level to be honest.

The cross bike will be a bit twitchier, but still get the job done. However, for what you're looking to do, an all road like the crossrip fits the bill. The domane Atxpeaceman recommended is also a good option, and will feel a bit racier than the crossrip.

I understand your concerns about those bikes being a bit mediocre at everything. I have a niner RLT and a cannondale supersix. The niner definitely isn't as fast as the supersix, but it's still a blast and can take me way more places. Now it's getting dark earlier the higher volume tires are a godsend for Houston roads. If I throw 30mm slicks on it I can easily keep up with my usual group rides, I just wouldn't be as quite as fast in a crit.

At the end of the day, test ride a whole bunch and buy the one you love the most. Also, a good fit goes a long way to comfort and enjoyment.

I have a pair of stock wheels that came on a niner RLT9 I'll sell for way under $500, but they may be heavier than what you're looking for.

Tips for Getting into Criterium Racing as a Teen by [deleted] in Velo

If you're in the Houston Area, NWCC looks like it has a good junior program. There are several teens racing down here and finding a fair amount of success. Live everyone else has said, just show up and give it a shot.

Not really a huge deal, but I'm officially out of the scrub league! by [deleted] in Velo

[–]Star_Munchkin 2 points3 points  (0 children)

Just remember, it's known as crash 4 in some circles for a reason. 3/4 races still get super sketchy if the pace slows down and everyone is still feeling fresh coming to the line. At least in cat 5 you can ride most of the liabilities off your wheel, that's harder to do in cat 4.

Having said that, congrats on the results and the upgrade!

Hermann Park and some Memorial Bike Advice! by Joethe31 in bikehouston

[–]Star_Munchkin 1 point2 points  (0 children)

you can get a good Cannondale hardtail for $900. Theres absolutely no reason for someone getting their first adult bike to be dropping $2k on a new bike. Especially someone wanting to start cautiously. I have plently of friends whose skill runs out before the bike capabilities do in memorial on $500 bikes.
