If a 15 ft x 20 ft room with an 8 ft ceiling is ventilated with a supply and a return of 300 ft3/min, how many air changes per hour are occurring?
6. A tank 20 ft long and 10 ft deep is 8 ft wide at the bottom and 18 ft wide at the top. In the bottom is an orifice having an area of 24 84 0.61? in. and å coefficient of discharge of 0.60. If the tank is full at the begin. ning, how long will it take to lower the water surface 6 ft? T
A 20-ft-by-30-ft swimming pool
is filled with water. The depth is measured at 5-ft intervals,
starting at one corner of the pool, and the values are recorded in
the table. Estimate the volume of water using the Midpoint Rule
with m = 2 and n = 3.

A conical container of radius 6 ft and height 24 ft is filled to a height of 20 ft of a liquid weighing 62.4 lb/ft. How much work will it take to pump the contents to the rim? How much work will it take to pump the liquid to a level of 4 ft above the cone's rim? The amount of work required to pump the liquid to the rim of the tank is ft-lb. (Round to the nearest whole...

A gate in a dam is 8 ft. high and 20 ft. long. If water is level with the top of the gate, what is the total force on the gate?
Problem 5 A barge 20 ft wide and 40 ft long is loaded with rocks as shown below. Assume that the center of gravity of the rocks and barge is located along the centerline at the top surface of the barge. If the rocks and the barge weigh 200,000 lbf, will the barge float upright or tip over? Show your work. 8 ft 20 ft
