A liquid food (density = 1200 kg/m³, viscosity = 0.07 Pa s) is to be pumped from an open constant level reservoir (that has a fluid level of 2 m) to another open tank, with the discharge point of the pipe to the second reservoir being 7 m above the level of the fluid in the first constant level reservoir. The liquid is to be pumped via a steel pipeline system at the rate of 40 gallons per minute. The pipeline system consists of a 4-in. nominal diameter suction pipe that is 20 m long and has a fully open diaphragm valve in it while the discharge pipe is a 1-in. nominal diameter pipe that is 30 m long and has two 90 regular threaded elbows in it. Assuming a pump efficiency of 75%, what should be the rating of the pump to accomplish this task?

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.
