QUESTION 4 (a) What are the Energy Grade Line (EGL) and Hydraulic Grade Line (HGL) in a pipe system? (1 mark) A factory draws its water supply from a mountain lake located 75 m above the factory (a) without pump. The factory is at present been supplied via 300 m of 20 cm diameter cast iron pipe. For control purposes, there are five gate valves and one globe valve in the line, as well as three standard 90...
3. (20%) Water of 15°C temperature is pumped at a rate of 0.01 m/s through the 800-m long and 10-cm diameter drawn tubing from the upstream reservoir at an elevation of 10 m to the downstream reservoir at an elevation of 30 m. The pump is located at an elevation of 10 m below the datum and at a distance of 350 m from the upstream reservoir as shown. (a) Find the values of the Reynolds number and the friction...

A water network is forned of five pipas, one treated water reservoir and one pump. The demands at junction nodes # 3, 4 and 5 are: d3 - 3 MGD, 1 MGD and ds - 2 MGD. The water surface elevation in the...
A reservoir A connected to B reservoir through a pipe that is 5 km long and 230 mm in diameter. The difference in water level of the two reservoirs is 70 m. At a distance of 2 km from the feeder reservoir, water is drawn at the rate of 40 litres/s . (a) Taking the friction factor as 0.008 and neglecting all other losses, determine the rate at which water enters the B reservoir. (b) Sketch the hydraulic grade line...
E Question-4 1.2 m 04=0 D Pipe 40-mm inside diameter 1.8 m Figure shows a siphon that is used to draw water from a swimming pool. The pipe that makes up the siphon has an inside diameter of 40 mm and terminates with a 25-mm diameter nozzle. Assuming that there are no energy losses in the system, calculate the volume flow rate through the siphon and the pressure at points B-E. 25-mm diameter 1.2 m Pp=0 Question - 5
