If the intensity of pressure in the smaller pipe is 125 kn/m2, determine:1. Loss of head, due to sudden enlargement, 2. Intensity of pressure in the larger pipe. and 3. Power lost due to enlargement.

In the test of the reaction turbine, the water flowing over the weir in the tailrace was found to be 39.8 ft3 /s. The leakage into the tailrace was found to be 1ft3 /s. The elevation of the centerline of the shaft above, the surface of tailwater was 12.67ft. The diameter of the turbine intake was 30in and the pressure at this section was measured by a mercury U-tube. The readings in the two sides of the mercury U-Tube were 10.556 ft and 0.900 ft, the zero of the scale being at a level 3.82ft below that of the centerline of the turbine shaft. The generator output was 391.8 kW, friction and windage loss 13.8 kW, iron loss 2.0kW and armature loss of 4.4kW. The specific gravity of the mercury used was 13.57. Calculate the efficiency of the turbine.
A horizontal pipe line 40 m long is connected to a water tank at one end and discharges freely into the atmosphere at the other end. For the first 25 m of its length from the tank, the pipe is 150 mm diameter and its diameter are suddenly enlarged to 300 mm. The height of water level in the tank is 8m above the centre of the pipe. Considering all losses of head which occur,determine the rate of flow. Take f = 0.01 for both sections of the pipe.

4. Two reservoirs, A and B, are connected by a pipeline which is 1300 m long. The surface of reservoir B is 10 m lower than that of reservoir A. There is a small hill between the two reservoirs with the highest point at 500 m along the pipe from A. If the pipeline has a diameter of 300 mm and a friction factor of λ = 0.008 then determine the following: (Ignore the minor losses and assume that the pipe is already flowing full and at a steady flow) (a) The flow in the pipe (b) If the lowest permissible absolute pressure head in the pipeline is 2.5 m of water, determine how high above reservoir A surface level the pipe can be laid so that the minimum pressure condition is satisfied.
