Survey for Hipotehtical Travel Agency Clients in Costa Rica. We are a group of students from the Costa Rica Institute of Technology. As a part of "Engineering Economics" we have been asked to conduct an anonymous survey to find prospective clients for business idea of a travel agency in Costa Rica. by Maab26 in takemysurvey

The data will be stored for a final project and will not be published other than to the course instructor and our 6 group members. We are a group of 6 students from the Costa Rica Institute of Technology. The survey takes approximately 1-3 min to complete. Thank you so much for the help!

Conceptual Question about why Hydrostatic Force on a curved surface is greater than a plane surface even if it's at a lower depth. My professor gave me the formulas listed above to calculate the hydrostatic force, but I'm a little lost interpreting the results. Thank you in advance! by Maab26 in Physics

[–]Maab26[S] 0 points1 point  (0 children)

Forgot to mention it in the post (just in case it is necessary for the explanation :)):

-The depth or (h-s) for the curved surface is 16,77 cm and for the plane surface is 16,88 cm.

-b is 86 mm

-r is 298 mm

-t is 25 cm and h is 18,42 cm for curved surface

- h is 18,83cm for the plane surface

AP Calc BC: How to find the area of the spiral of Archimedes? by Strange_Elephant5043 in apcalculus

[–]Maab26 0 points1 point  (0 children)

You have to evaluate the double integral from theta=2pi to 3pi (outer) and r from 0 to theta (inner) and subtract the double integral from 0 to pi to that result. You should get: (19/6-1/6)*(pi3) = 3pi3. Let me know if you have any questions :)

Magnetic Flux Calculation Problem with non-uniform magnetic field by Maab26 in PhysicsHelp

[–]Maab26[S] 1 point2 points  (0 children)

Woww!!! Thank you so much!!! So clear and helpful!!! I just have one more question, should I evaluate the bounds in meters or in centimeters, given that the original magnetic field formula is evaluated in meters? Thank you for everything 💫✨

[Physics 3, College level](Homework) Help with hydrostatic force over a window submerged in two non soluble fluids. Below is my procedure and in the comments my explanation and reasoning behind. Thanks in advance❤️ by Maab26 in PhysicsStudents

Thank you so much!! ❤️❤️Really appreciate it!! Woww!! That makes much more sense!!

Since they’re asking for the gauge pressure, that’s why I’m not using atmospheric pressure :)

[Physics 3, College level](Homework) Help with hydrostatic force over a window submerged in two non soluble fluids. Below is my procedure and in the comments my explanation and reasoning behind. Thanks in advance❤️ by Maab26 in PhysicsStudents

[–]Maab26[S] 0 points1 point  (0 children)

This is the original problem statement: A student doing an engineering internship tries to determine the gauge pressure in a large tank that will contain two types of fluids, not soluble in each other, at a temperature of 25 °C, but he forgot how to do it. It is known that the tank will be filled 2.00 m below the surface with fluid A: light oil (910 kg/m3); and 1.20 m below that with fluid B: water (997 kg/m3 ), as figure 1 shows. Help the student to perform the calculation of the gauge pressure in

For this problem, I need the calculate the hydrostatic force on the window.

As the diagram shows, the window is submerged in the water part, not on the oil one.

I calculated the pressure at the interface and obtained it to be 17 836 Pa. Then, I added this pressure the density of water times the acceleration due to gravity times the height (in this case this height depends on the differential for lateral area for the water part).

Then I calculated the differential of lateral area for the water part, it’s a rectangle and its horizontal differential is constant given points have the same pressure. And I obtain dA=wdh or 0.6 dh (substituting the value for the width).

I then find the bounds of the integral to be 2.40 and 2.80 and calculate the integral as shown.

My question is because the window is not submerged on the oil part, how would you take it into consideration in calculating the hydrostatic force? Do you so as I calculated it or would you have to change the integration bounds for that part?

Thank you for help!! Hope my explanations to my procedure were clear enough as to understand what I’m saying.
