Answer to Question #64140 in Mechanics | Relativity for Janette A. Merenillo

Question

4.A right circular cylindrical tank with a depth of 10m and a radius of 5m is half filled with water. Find the work necessary to pump the water to the top of the tank.
5.A water tank in the form of an inverted right circular cone is 2m across the top and 1.5m deep. If the surface of water is 0.5m below the top of the tank, find the work done in pumping the water to the top of the tank.
IX- LIQUID/FLUID PRESSURE
1. The face of a dam adjacent to the water is vertical and rectangular in shape with width 50ft and height 10ft. Find the total force exerted by the liquid on the face of the dam when the water surface is level with the top of the dam.
2. The face of the dam adjacent to the water has the shape of an isosceles trapezoid of altitude 20ft, upper base 50ft, and lower base 40ft. Find the total force exerted by the water on the dam when the water is 15ft deep.
