vious Problem List Next (1 point) A rectangular tank that is 8 feet long, 3 feet wide and 9 feet dee is filled with a heavy iquid that weighs 120 pounds per cubio foot ch patteow, assume that the tank is initially full. Your answers must include the correct units. (You may enter lbfor lb f for ff-lb.) (a) How much work is done pumping all of the liquid out over the top of the tank? (b) How much work...
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...
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
