A compressor is to be used to draw air from the outdoors where the conditions are 26.5 C and 100.04 kPa. The desired volume flowrate is 0.28 cubic meter per second. The air will pass through a duct with a diameter of 14 cm. The vertical height of the duct is 11.7 m. If the efficiency is 88.0 %, determine the required power in W. Assume a friction factor of 0.023.

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 Vị = 80 m/s STEAM W P2 = 10 kPa x2 = 0.92 Vz = 50 m/s

A hydraulic vane pump running at 1800 rpm develops 2 L/s flow at 750 kPa. Volumetric efficiency is .85 and overall efficiency is 0.8. Determine the Mechanical Efficiency, nm. O 0.975 O 0.80 O 0.941 O 0.85 O 1.06

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

please help me

= (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. =

A hydraulic vane pump running at 1800 rpm develops 2 L/s flow at 750kPa. Volumetric efficiency is .85 and overall efficiency is 0.8. Determine the Theoretical Flow Rate, QT. O 0.00235 m³/s O 0.0025 m³/s O 0.0027 m³/s O 0.0017 m³/s

The centrifugal pump is operating under steady flow condition delivers 2270 kg/min of water from an initial pressure of 82740 Pa to a final pressure of 275800 Pa. The diameter of the inlet pipe to the pump is 15.24 cm and the diameter of the discharge pipe is 10.16 cm. Calculate the work of the system in kJ/ min.
