Q.1 Assume that with the farmer’s plan the resistance from friction in the system will contribute exactly 5 vertical feet to the system’s total. For each of the following possible heights from the surface of the water source to the top of the tank, select Yes if it meets the constraints of the plan as specified. Otherwise, select No.
The constraints are the pressure in psi, which depends on vertical height and vertical height itself.
Vertical height: The vertical height is 58 feet, and it contains 5 feet of vertical height lost due to the resistance. Thus effective 53 feet.
Clearly anything above 53 feet cannot be met out of existingpump.
20feet: <53 feet, so can be used. Let us check the pressure now. The inlet is 4 above ground and 5 feet above the water surface. Thus, pressure is 0.43psi*(20-5) = 7.95, which is less than the pressure required 10 psi.
Hence will notwork...NO
40feet: <53 feet, so can be used. Let us check the pressure now. The inlet is 4 above ground
