Applied Fluid Mechanics

A fluid is a substance that is continuously deformed by the application of shear stress. The rate of deformation of a fluid depends on its viscosity. The fluid tries to flow when it interacts with some other system.

Question

The value of (NPSH) for a pump is given by the manufacturer as 10 ft. Water is being pumped from a reservoir at
min
atmospheric pressure at a rate of 30 ft /s to a tank at atmospheric pressure. The water level in the reservoir is 5 ft below the
pump. If the total head loss in the suction pipe is 5 ft, is the pump safe from cavitation effects?
If a 2-in schedule 40 pipe of 150 m length was used downstream of the pump, what is the power delivered to the fluid? You
may assume that the friction factor in the pipe is equal to 0.004.

Show complete solution and formulas used. Show the schematic diagram too. Calculate the required pipe diameter to avoid cavitation, if the pump delivers Q = 30US gallon/min water from a closed tank, where the pressure (above the water level) is p = 40kPa. The equivalent length of the smoothened concrete pipe on the suction side is 12m while the suction flange of the pump is 8m below the water level. The vapour pressure at the given water temperature is 2.8kPa. The required net positive suction head is NPSHr = 3.2m.
On a trip to the beach (Patm 1 atm or 101.3 kPa), a car runs out of gasoline and it is necessary to siphon gasoline from a Good Samaritan's car. The siphon is a hose with a small diameter and to start the action it is necessary to insert one end into the tank full of gasoline, fill the hose with it through suction and then put the other end in a can that is placed under the tank level. The difference in pressure between point 1 (on the free surface of the gasoline in the tank) and point 2 (at the outlet of the tube) causes the liquid to flow from the highest elevation to the lowest. In this case, point 2 is located 0.75 m below point 1, and point 3 is 2 m above 1. The siphon diameter is 4 mm and friction losses in it must be ruled out. Determine: a) theminimum time to bring 4 L of gasoline from the tank to the can and b) the pressure at point 3. The density of the gasoline is 750 kg / m3.
