A pump will be used to convey water from a lake into a pressurized storage tank for a secluded cabin vacation house. If 1000 gallons of water must be delivered in 10 minutes or less, will a pump that adds 3 hp to the water be sufficient? Explain and support your answer with calculations.   
Assume 2 atm for the pressurized tank, and 20 ft difference in elevation from lake to water surface level in pressurized tank.

ANSWER: 3 HP pump will work.

Water is pumped by a motor-pump unit from a lake to a storage tank 17 m above at a rate of 120 L/s. The storage tank is open to the atmosphere. The motor consumes 25 kW of electric power and the motor effciency is 95%. Disregarding any changes in kinetic energy of the water, determine (a) the overall effciency of the pump-motor unit, (b) the effciency of the pump and (c) the shaft power supplied by the motor to the...

An industrial pump is to be used to supply water from Lake Bonno to an agricultural field located 500 m away from the lake, and at an elevation of 20 m above the surface of the lake. If the horse-power of the pump is 45-hp, what is the discharge that can be delivered by using a pipe of diameter D = 0.4 m and a friction coefficient of f = 0.015? Neglect all minor losses. Is the flow laminar or...

A pump is used to carry water (T =60 oF and ν = 1.217×10-5 ft2/s) from a large tank (elevation of surface = 30 ft and at atmospheric pressure) through a pipe to the exit (elevation 60 ft) at a rate Q = 1.5 cfs as shown below. The pipe is made of cast iron (ε = 0.00085 ft). The pipe segment before the pump has length L = 500 ft (three horizontal sections of 160 ft each and two...

A farmer wants to pump water from a river to a very big open storage tank nearby using a 55-m long, 16-cm diameter plastic pipe with 5 threaded 90° regular bends, 5 threaded 45° regular bends, and one fully open gate valve. The water velocity near the river surface is 2.7 m/s and the pipe's inlet is placed in the river normal to the direction of water flow to take advantage of this water speed. The elevation difference between the...

Design a cast iron (kd=8*10‐4 ft) pressurized system (pipe diameter) that would convey water at 2 ft3/s from two elevated tanks separated 200 ft long. The difference in water surface elevation between the tanks is 20 ft and the kinematic viscosity is 1.217*10‐5 ft2/s. Along the system the entrance loss and the exit loss have a KL of 0.5 and 1, respectively. Two 90 degrees bends are present (KL=3) and a global valve (KL=10) is also installed along the system.
