Question

You are working in a new and not very well understood area of fluid You wish to predict the power delivered by a turbine, and you kn dynamics, such as fluid flow through very low permeability the outer and inner diameters of the wheel, the angle of the guid formations. You would like to build a laboratory model and use the vanes, the discharge (another term for volumetric flow rate), wa measurements you obtain there to understand the real word probler density and rpm. You will need to use the power equation P-TW So far, you've identified the six key variables that are relevant, including the one you would like to solve for. What approach can you in addition you should use: take to better understand how to scale up your lab measurements of the small model to the full size problem? Select one: O a. Buckingham pi theorem Select one: O b. Couette flow O a. Use the hyrdostatic equations to estimate the pressure O c. Conservation of mass O b. Apply conservation of mass and assume steady state flow d. Conservation of angular momentum O c. Find the dimensionless parameters using the Buckingham PI theorem You are designing a power washing tool that people can use to hydrostatic equation can be used to: quickly clean the exterior of their homes. One requirement is that using the tool to wash windows won't cause a typical home window ct one: to break. Given that you have the maximum force such a window ca withstand, and you have the dimensions of the nozzle of the power a. Estimate the power required in a pump to lift water 10 ft a washer, you want to calculate the maximum inflow allowed without rate of 10 gallons/minute fisking damaging windows. Which of the following approaches woul b. Estimate the amount of time it would take for a tank to dri be most useful. from a hole near the bottom on the side of the tank Select one: c. Calculate the pressure on the front end of a tank trailer fille O a. The hyrdostatic equation with oil when the truck pulling it has to rapidly decelerate O b. Poiseuille flow d. Estimate the pressure in a tank that has a manometer attac O c. Conservation of mass O d. Conservation of linear momentum

Answer 1

The correct answers are marked with green. I am pretty sure of these answers. Please dear thumpsup for the answer. Thank you.
