2. Water flows at a rate of 60 L/s from a main reservoir to a subsidiary through a 600 m long, 185 mm diameter asphalted cast iron pipe as shown in the figure. The pipeline contains a gate valve, a globe valve and 4 standard 90° elbows. The entrance and exit are square edged, and all fittings are screwed ends, determine, You need Kinematic viscosity of water, 1 x 10-6 m/s2 (a) The friction head loss in the pipe, (b)...
Question 1 50 marks Part A (30 marks) In a proposed water supply system, two large reservoirs will be connected with a pipeline 9 km long and with an elevation difference of 72 metres between the full water levels of the reservoirs. The pipe will be required to convey a minimum discharge of 450 L/s. The proposed pipe material is UPVC. Fittings in the pipeline include one 90° short radius elbow and one gate valve fully open. Pipeline entrance and...

Problem 3 A pipeline delivers water from Reservoir 1 to Reservoir 2 as shown in the following figure. The water levels at Reservoirs 1 and 2 are 50 ft and 20 ft, respectively. A globe valve is installed in the pipeline with a minor head loss coefficient k 10. The pipe from Reservoir 1 to the globe valve is 1000 ft long and 6 inches in diameter. The pipe from the globe valve to Reservoir 2 is also 1000 ft...
