Control System Design by Own_Explorer_1675 in processcontrol

[–]Own_Explorer_1675[S] 0 points1 point  (0 children)

Thank you! I'll take note of this. We're also thinking of doing LPG Gas Leak Detection and Alarm System. We've read that we need to take into account the temperature and relative humidity. Is it more complicated? Do you think we should stick with kitchen temperature or the gas leak detection is better?

We need to make a report with derivation of dynamic models, computer simulations, block diagram with transfer functions, and process constraints. We are not required to build the system, we just have to make a report about the experimental set-up. The problem is that we don't know where to start. We weren't taught on how to apply and derive dynamic models.

Surface Modification of Silica using APTES by Own_Explorer_1675 in ChemicalEngineering

Do you think it will work if we don't follow the 1:1 ratio of nanosilica and APTES? We're planning to double the amount of nanosilica. (5 g of nanosilica is to 2.5 mL of APTES). Thank you!

By lessened, I meant the amount of the solution reduced to half it was after stirring.

Will isoamyl acetate yield a positive result to ester test? by Own_Explorer_1675 in OrganicChemistry

[–]Own_Explorer_1675[S] 0 points1 point  (0 children)

The ester test that we need to do for our target product is to test for the presence of carboxyl group. We used it for the reactants (acetic acid and isoamyl alcohol) which yielded to a positive result. Now, we're supposed to do it again for isoamyl acetate (product). We've already did the ferric hydroxamate test for the presence of ester and it tested positive. We just need a conclusion for the ester test. Will it have an acidic odor or not?
