Chapter 5, Problem 48EP
A siphon pumps water from a large reservoir to a lower tank that is initially empty. The tank also has a rounded orifice 20 11 below the reservoir surface where the water leaves the tank. Both the siphon and the orifice diameters are 2 in. Ignoring frictional losses, determine to what height the water will rise in the tank at equilibrium.

For a pumper truck pumping water to a fire, the back pressure is the additional pressure on the pump caused by the height of the nozzle. (Another way of thinking of back pressure is as the minimum pressure the pumper must produce in order to make water flow out the end of the nozzle.) Consider a pumper at street level pumping water through a hose to firefighters on the top of the ninth floor of a building. If each floor is 16 feet high, what is the head of water at the mouth of the nozzle?
A large container filled with water and uncovered for use in fighting fires in an ethylene production plant. Water from this tank is pumped into the nozzle when needed use. This fire suppression system is designed to be able to transmit 1890 L/min of water at a pressure of 15 bar (relative pressure). If we ignore the difference in height between the water level in the tank and pump, there is no change in diameter of pipe and nozzle, pump efficiency is 70%. Ask how much work (hp) is required to the pump to achieve the desired pressure and flow would like?
I2
4.2, there is friction in the piping, which means that an additional pressure equivalent to a height of 100 m is needed to pump the water from the bottom tank to the top tank. What is the minimum power required when accounting for friction? By what percentage has friction increased the minimum power required? Remember to show your calculations.
