Water is being pumped into a leaky inverted conical tank at a rate of 10 m^3/h. The tank has a height of 9 m and the diameter at the top is 6 m. If the water level is rising at a rate of 0.2 m/h when the height of the water is 6 m, how fast is the water leaking out at that time?

Water at 200 Fahrenheit is pumped from a storage tank at the rate of 50 gallons/minute. The motor for the pump supplies work at the rate of 2 hp. The water goes through a heat exchanger, giving up heat at the rate of 40,000 BTU/minute(Q Net In), and is delivered to a second storage tank at an elevation 50 feet above the first tank. What is the temperature of the water delivered to the second tank?

Water is being pumped through a horizontal pipe that is 36.0 m long and 13.5 cm in diameter. A pump maintains a gauge pressure of 742 Pa at a large open tank at one end of the pipe. The other end of the pipe is open to the air. If this pipe is replaced by a second one of length 9 m and diameter 5.0 cm, what gauge pressure must the pump provide to give the same volume flow rate...
