- I am trying to find the mass flow rate that is extracted from the turbine I am getting nubers near 2.9 for a result. how do I solve this.arrow_forwardA 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. (a) 52 fps, (b) 50 fps, (c) 54 fps, (d) 56 fpsarrow_forwardThe steam from the nozzles of a single wheel impulse turbine is 600m/s and at 20degree to the plane of the wheel. The blade wheel rotates at 3000rev/min and the mean blade radius is 590mm. The axial velocity of the steam at exit from the blade is 164m/s and the blades are symmetrical. Calculate 1: The blade angles; 2: The diagram work per unit mass flow rate steam. 3: The diagram efficiency. 4: The blade velocity coefficient.arrow_forward
- = (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. =arrow_forwardIn a turbine 4500 kg/min of air expands polytropically from 425 kPa & 1360K to 101 kPa. The exponent n is equal to 1.45 for the process. Calculate the heat and work steady flow.arrow_forwardAt inlet to a certain nozzle the specific enthalpy of the fluid passing 3500 kJ/kg and the velocity is 70 m/sec.

- A blade pair in an axial flow compressor is being designed. The axial flow component of gas velocity is 174m/s. The engine diameter at the mean blade height is 0.73m and the blade height at the rotor inlet is 0.21m. The rotor's absolute inlet flow angle is 26 degrees. The stagnation conditions at the inlet to the blade pair are 298K and 130kN/m² Using Cp 1.005k/kg/K, R-0.287k/kg/K, and taking the ratio of specific heat capacities as 1.4, calculate the engine mass flow rate to the nearest kg/sarrow_forwardWrite a steady flow energy equation and simplify it for turbine and compressor?arrow_forwardA sump pump (used to drain water from the basement of houses built below the water table) is draining a flooded basement at the rate of 0.85 L/s, with an output pressure of 3.05 × 105 Pa. a. The water enters a hose with a 2.8 cm inside diameter and rises 2.4 m above the pump. What is its pressure at this point, in pascals? You may neglect frictional losses. ( dont forget to convert the diameters of pipes into meters.) b. The hose then goes over the foundation wall, losing 0.35 m in height, and widens to 4.4 cm in diameter. What is the pressure now, in pascals? You may neglect frictional losses. ( dont forget to convert the diameters of pipes into meters.) Note: answer iS NOT 3.29 x 10^5 for either of these.arrow_forward
