Exercise 2: A pipe brings water, with a mass density Pwater, from a dam to the turbine of a hydroelectric plant. The cylindrical pipe, of constant diameter D30.0 cm and length L200 m, ends horizontally, its axis being located at H- 120 m below the free surface of the water in the dam of very big capacity. The departure of the pipe is at Ho- 20 m below the level of the free surface of the dam considered constant. The...
Question (20 marks Analysis only required Water at 15°C is discharged freely to atmosphere from a reservoir at 18 L/s through two horizontal pipes in series and a pump-motor assembly in between as shown in figure below. First pipe-A is made of cast Iron and is 20m in length with a 60mm dia. The second pipe-B is 35 m in length, has a 40 mm diameter with friction factor 0.0331. The pipe entrance from reservoir is sharp edged. Neglect any...

Question D.1 A2 Not sure Water flows between two tanks connected by a 100 m long pipe as shown in figure D1-1 below The tanks have a free surface height difference of 15 m and are both open to atmosphere. The first 30 m of pipe from the upper tank (section 1) has an internal diameter of 50 mm and a friction factor of 0.006, whilist the remaining 70m of pipe (section 2) has an internal diameter mm and a...
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)...
Water flows from one large reservoir to another via a pipeline which is 0.9 m in diameter, 15km long, and for which f-0.04. The difference in height between the water surface levels in the two reservoirs is 50m. (a) Ignoring the minor losses in the pipeline, calculate the flow rate between the two reservoirs. (b) Assuming that the pipeline entrance and exit are sharp and that the minor losses are as in Table 1, calculate the discharge now. What is...
Q4. A pump draws water from a large reservoir and delivers it to another reservoir whose water surface is 10 m higher than the pump centreline and that the pump is 1.5 meter above the suction reservoir. The total suction and deliver pipe used is 21.1 m in length, 9 cm in diameter and has a Darcy friction factor f0.0339. The pump operates at 750 rpm and its characteristic performances are given in table below: Q (m3 s H (m)15...
A pump carries water at a temperature of 30 ° C from one tank (A) to another (B). The diameter of the pipe leaving tank A and reaching the pump is 4 inches. The diameter of the pipe leaving the pump and reaching tank B is 3 inches. The pump motor increases the fluid pressure by 3 kgf / cm2 (ΔP), and generates a power per unit of mass of 300 J / kg. Calculate the height difference (ΔZ) between...

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...
