2.3 (c) The population of a city is 800000 and it is to be supplied with water from a reservoir 6.4 km away. Water is to be supplied at the rate of 140 litres per head per day and half the supply is to be delivered in 8 hours. The loss of head due to friction in the pipeline is 60 m. Find the diameter of the pipe. Take f = 0.04.
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?
4.4 A tank containing water is placed on a trolley, which is attached to the wall by a cable, as shown in Fig. 4.28. A pipe bend is connected to the tank through which a jet of water is coming out with a velocity of 7.5m/s. If the diameter of the nozzle is 40 mm, calculate the tension in the cable. 7.5 m/s 30% Fig. 4.28 [Ans: 61.215 N]
The plunger diameter of a single acting reciprocating pump is 115 mm and the stroke is 230 mm. The suction pipe is 90 mm in diameter and 4.2 m long. If cavitation takes place at the suction head of 4 m, the barometer stands at 10,3 m of water, and the water level in the sump is 3 m below the pump cylinder axis. 2.1 Find the maximum allowable speed to operate the pump 2.2 What power is expected in overcoming friction at this speed, take f=0.01
1. A pipe with a radius of 0.1 m used to drain an entire full water tank within one hour. The tank is a cylinder with a height (h) of 3 meters and a diameter of 5 meters.How fast will the water need to move through the pipe? Draw an illustration that will help you visualize the problem. Indicate important labels and measurements in your illustration.
The pressure at an opening in the side of a tank of water is 40 lb/in^2 greater than atmospheric pressure. What will the velocity of the water be as it leaves the opening?
Water of density ρ issues from a spigot of circular cross-section into the atmosphere, as shown in Figure P4.39. At the flange, the velocity is V . The diameter decreases from D at the flange to D at the exit. Ignoring losses, (a) Find the gauge pressure at the flange in terms of ρ and V . (b) Find the magnitude and direction of the force exerted by the water on the spigot in terms of ρ, D and V (ignore the weight of water contained in the spigot).

1. Water flows steadily through a smooth, circular, horizontal pipe. The discharge rate is 1.5 ft3/s and the pipe diameter is 6 in. Find the difference in the pressure between two points 400 f t apart if the water temperature is 60°F. 2. A 2000-gallon swimming pool is to be filled with a 0.75 in. diameter garden hose. If the supply pressure is 60 psig, find the time required to fill the pool. The hose is 100 f t long, with a friction factor equal to 0.02.
Problem 2. A garden hose with an attached nozzle is used to fill a container with water. The nozzle starts at a diameter of 2 cm and is then reduced to 0.8 cm at the exit. In 50 seconds, the nozzle and hose are able to fill the container with 10 gallons of water. Find the volumetric flow rate (m³/s), the mass flow rate (kg/s), and the average velocity (m/s) at the at the nozzle exit. Assume the density p of water is 1000 kg/m³.
1. A propeller 2 f t in diameter moves at 20 f t/s in water and produces a thrust of 1000 lbf . Find the ratio of the upstream to downstream velocities, and the efficiency. 2. An airplane flies at 140 mph at sea level at 60◦F. The propeller diameter is 8 f t, and the slipstream has a velocity of 200 mph relative to the airplane. Find: (a) The propeller efficiency. (b) The flow velocity in the plane of the propeller. (c) The power input. (d) The thrust of the propeller. (e) The pressure difference across the propeller disk.
A groundwater well with produces 80 m/hr. and has a hydraulic conductivity of 20 m/d. Calculate the following: a. The length of the screen b. The diameter of the delivery pipe. c. The velocity head and the friction losses in the delivery pipe. d. What is the required power of the pump if the abstraction efficiency was 70%?
