If the mass flow rate of steam is 11 kg/s in steadystate turbine, find the shaft output (W) in kW P1 = 10 MPa I1 = 450°C V1 = 80 m/s STEAM W P2 = 10 kPa x2 = 0.92 Vz = 50 m/s

Water flowing at 0.5 m³/min enters the turbine of a micro hydroelectric generator and delivers a shaft work of W₁ = 2,500 J/kg. What is the power delivered by the generator if it works at 95% efficiency, n = 0.95?

this question is very much related to mechanical engineering. The concept of propeller and supercharger is needed

Consider a cycle which uses a pump to increase the pressure of liquid water from a lake by AP = 4 MPa. The water enters a 20 cm diameter pipe and exits via a 12 cm diameter pipe. If m = 200 kg/s, and you ignore changes in potential energy, what would Win be? (a) 107 kW (b) 97 kW (c) 87 kW (d) 7 kW

A water pump is used in a heating system to deliver hot water at 91 GPM and 121 ft w.c. The pump efficiency is 90%. What is the water horsepower?

Find these 5 things

= (a) A centrifugal pump, with salt water as the working fluid, has the impeller blades rotating at 750 rpm. The fluid enters the blades in the radial direction, i.e. at an angle of α₁ = 0°, and exits the blades at an angle of 35° from the radial direction. i.e. α₂ = 35⁰. The inlet radius and blade width are r₁ 12.0 cm and b₁ = 18.0 cm, respectively. The outlet radius and blade width are 1₂ = 24.0 cm and b₂ = 16.2 cm, respectively. Assuming 100 percent efficiency, and if the volumetric flow-rate through the pump is 0.573 m³/s, compute the net head produced by the centrifugal pump. Furthermore, calculate the required brake horsepower in Watts. Take the density of salt water to be p 998.0 kg/m³. =
