Water at 20 oC is pumped at a rate of 9.0 m3/h from a large tank resting on the floor(open to the atmosphere) to the top of an absorption tower, 5.0 m above the floor. Thedischarge is at atmospheric pressure. The pipe is 50 mm ID, and the friction losses are 2.5J/kg. The pump can supply 0.1 kW to the fluid. Find the minimum water level in the tank thatyou can achieve with a pump with that power.

An open reservoir on ground level is used to store water to be pumped up to an overhead tank (also open) 200 ft ave ground. Calculate the work done by the pump (in J/kg) to give an exit velocity of 40 m/s. Ignore friction and use alpha = 1.00. Evaluate the pressure term Evaluate he kinetic energy term Evaluate the potential energy term Hence calculate the work done by the pump What minimum power of pump (in KW) would be needed to provide a mass flowrate of 0.27 kg/s Training

how to do

This is thermodynamics subject. I need complete solution (step by step process) with given. Thanks

The pressure after the pump in a 6-inch inside smooth pipe conducting water is 20 psia. The water is dischargedat an open tank 100ft. from the pump. Calculate the rate of discharge of water in ft3/s.

A 20-KW motor with 80% efficiency drives a centrifugal pump delivery 0.08m3/sec against a head of 20m. Determine the pump efficiency

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.

A pump is required to transfer water at the rate of 350 kg/s from an open sump to an open storage tank located 30m above the pump. The sucLon pipe is 350mm in diameter and 12m in length and the delivery pipe is 550mm in diameter and 40m in length. Calculate:(a) The maximum height at which the pump may be placed above the sump, so that pressure at the inlet is not less than -80 kPa (gauge) (b) the energy to be supplied by the pump per unit mass of water transferred (c) The input power required by the pump, which is 60 % efficient

Water is flowing at the rate of 1.676 m/s in a 3.068 inches’ diameter horizontal pipe at apressure p1 of 68.9 kPa. It then passes to a pipe having an inside diameter of 2.067 inch. Thedensity of the water is 998 kg/m3.a) Calculate the new pressure p2 in the 2.067inch pipe. Assume no friction losses.b) If the piping is vertical and the flow is upward, calculate the new pressure p2. The pressure tap for p2 is 0.457 m above the tap for p1.c) Compare and discuss your answers in 2 (a) and 2(b).
