How much work is required to pump the water out of the top of a half-full 10 foot long horizontal cylindrical tank that has radius 3 ft. ? The weight density of the water is 62.4 lb/ft3. Round to a whole number. ANSWER IS 37,697. Please write out every step.
Pumping a conical tank A right- circular conical tank, point
down, with top radius 5 ft and height 10 ft is filled with a liquid
whose weight-density is 60 lb/ft^ 3 . How much work does it take to
pump the liquid to a point 2 ft above the tank? If the pump is
driven by a motor rated at 275 ft-lb/sec (1/2 hp), , how long will
it take to empty the tank? Must work the integral out by...
(2) The work required to pump the fluid from a tank (between a units and b units above the bottom of a tank) of constant mass-density p out to a height h above the bottom of the tank is given by W- pg(cross-sectional area at y)(distance fluid at y needs to be lifted) dy where g is the acceleration due to gravity and y is the distance from bottom of the tank. Note: Water has a mass-density of p 10...
9. a. A spring has constant k-5lb./in. Its natural length is 12 inches. What is the work required to compress it to 9 inches? b. A 100 ft. cable weighs 40 lbs. Find the work done in winding the cable onto a winch, if the cable is hanging vertically c. An unknown positive charge q is placed at the origin. The force F (in Newtons) with which this charge repels a unit positive charge is given by F-kq/r, where k...

A tank is full of water. Find the work w required to pump the water out of the spout. (Use 9.8 m/s for 9. Use 1000 kg/m as the weight density of water. Assume that = 4 m, 4 m, c = 12 m, and d = m.) W- Enhanced Feedback Please try again. Try dividing the tank into thin horizontal slabs of height Ax. Let x be the distance between each slab and the sout. If the top surface...

a rectangular water tank 10' wide 10' long and 6' tall is buried underground so that its top is 4' below ground level. assume water weighs 62.4 pounds per foot cube and the tank is full of water. how much work does it take to pump out 2/3 of the water in the tank to a height 2' above ground level?
Water in a vertical cylindrical tank of height 29 it and radius 4 ft is to be pumped out. The density of water is 62.4 lb/R. (6) The tank is full of water and all of the water is to be pumped over the top of the tank. Find the approximate work for the slice as shown. Use Delta or A from the CalcPad. Leave in your answer. 32118.5281 ( 29 - y) Ay Find the endpoints for the integral...
9. (9 points) Suppose we have a triangular tank full of water. The tank is 2 meters long, half a meter tall and a meter wide (see below). Set up an integral for how much work is done when pumping water out of the top of the tank. Use p for the density of water and g for the acceleration due to gravity. Do not evaluate the integral. 0.5 m 1 m
