a SSSF control volume has three inflow streams, where each inflow stream has a mass-flow-rate, m(dot) = 2kg/sec. In addition, there are two outflow streams, where one of these outflow streams has a mass-flow-rate, m(dot) = 5 kg/sec. What is the mass flow rate of the second outflow stream in kg/sec?

6.5-7

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

Q. The velocity of steam leaving a nozzle of Turbine is 896 m/s and the nozzle angle is 20°. The blade velocity is 300 m/s and the blade coefficient is 0.79. Assuming the mass flow rate as 1 kg/s and the runner blades are symmetric. Determine the power developed in kW
