6. The fill line for a tank swages up from 8" Schedule 40 pipe to 16" Schedule 40 pipe. The velocity entering the tank must be limited to 3 ft/s to avoid a static charge build up in the tank. A) What is the maximum velocity allowed in the 8" section of pipe? B) What is the maximum volumetric flow rate entering the tank?

b) A thin layer of water flows down along the surface of a hill. The water is exposed to the atmosphere. Which of the following head may increase as the water flows down?

7.45 If the fluid motor has an efficiency of 78 percent, how much power is delivered by the motor? 15-in Schedule 80 steel pipe 25-in Schedule 80 steel pipe Oil -Motor Flow 38.5 in Mercury sg = 13.54 Answer is 1.24 Hp. Please shw how to get ture.

A) Calculate by hand the net head delivered and the efficiency of the pump at flow rate of 63 L/s. B) Use excel sheet and its formula to solve the equations and plot the pump head, power input, and efficiency versus the pump flow rate

Please find attached questions. Thank you.

The pump delivers water from the lower to the upper reservoir at the rate of 2.0 ft. The head loss S between the suction pipe inlet and the pump is 6ft and that between the pump outlet and the upper reservoir IS 12ft. Both pipes 6 inches Schedule 40 steel pipe. Calculate a)The pressure at the pump inlet in Psi,b) The pressure at the pump outlet in Psi,c) The total head on the pump in ft, andd) The power delivered by the pump to the water in Hp

Question 3.) A Pitot tube is used to find stagnation pressure in relation to the static pressure port in an aircraft. The aircraft is flying at an altitude of 10 kilometers on a standard day. The pressure that is measured is 16.4 kPa gage. Find the following: 1.) Atmospheric conditions at an altitude of 10 kilometers, use online resources if needed 2.) If you assume the flow is incompressible, find the following: a. The flight speed b. Mach number of the aircraft

1) An engineer wants to increase a pipeline diameter but maintain the volumetric flow rate. The entrance pressure must ________. increase decrease stay the same not enough information   2) Water is pumped down a pipeline. The feed to the pipeline is switched to honey, which has a higher viscosity. The pressure at the entrance of the pipeline will need to ________________ to maintain the same volumetric flow rate. increase decrease stay the same Please Explain Your "Original" Answers!
