A steam turbine developed 2372.2 hp when its inlet condition is 1300 BTU/lb enthalphy and 400 ft/s velocity and steam flow of 200 lb/min. The exit enthalphy is 800 BTU/min. Find the exit velocity.

There are two turbine stages with a reheater in between, as shown below and the following conditions are provided. Assume the mass flow rate of air = 1 Kg/s. Turbine stage 1 Stream 1 2 3 4 Reheat combustor P (kPa) T (K) 1200 350 350 100 1200 1200 3 Turbine stage 2 h (kJ/kg) W cycle • Determine the total work developed, which is the sum of the work developed by the first stage and the work developed in the second stage. • Determine the heat added in the reheater. • If the reheat is turned off, streams 2 and 3 no longer exist and we go directly from 1 to a new state at stream 4. What is h4 and what is the work generated in the turbine in this case?

Apply the first law of thermodynamics to nozzle. Assume that the process is reversible adiabatic. Draw the neat sketch and lable inlet and outlet properties

= (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. =
