Q4. Water from a reservoir is conveyed via a pipeline of constant diameter and 1000m length to a turbine situated 90m below the reservoir surface level. The velocity of flow through the pipeline is 5m/s and the energy loss due to friction in the pipeline is 200J/kg. The water leaves the turbine at atmospheric pressure (100 kN/m2) and with negligible velocity. Assuming an efficiency of 85% for the turbine, determine: a). Pipeline diameter b). Pressure at entry to turbine c). Turbine power output. Take f = 0.025
2. In the system shown in figure below, a pump draws a solution of water from a storage tank through a pipe with cross sectional area 0.05ft². The velocity in the suction line is 3 ft/s (0.914 m/s). The pump discharges through a pipe with cross sectional area 0.02 ft² to an overhead tank. The end of the discharge pipe is 50 ft (15.2 m) above the level of the solution in the feed tank.

Problem 1. Air in a diffuser (diffuser: A device that increases pressure of a fluid by decreasing fluid velocity). Air enters the diffuser at a inlet outlet steady velocity of 200 m/s, T= 10 °C, and P = 80 kPa. The inlet area of the diffuser is 0.4 m². The air leaving the diffuser (outlet) has a very diffuser small velocity compared to the inlet velocity. Find the mass flow rate (kg/s) of the air and the temperature (°C) leaving the diffuser.

QUESTION 3 A Pelton wheel with a needle-controlled nozzle develops 1 050 kW against a gross head of 300 m. The loss of head due to friction in the pipeline and the nozzle is 60 x V, where V is the flow rate in m/s. Assuming that the overall efficiency of the wheel remains constant at 83%, determine the percentage reduction in flow rate required when the power developed is reduced to 710 kW by closing a valve on the pipeline partially.
