Albert bought a portable device to pump his truck tyres. On the manual, he found out that the device is a single stage, single-acting air compressor. Air delivery for this device is 30 bar at a speed of 1500 rev/min. The atmospheric condition of his location is 87 kPa and 20 ˚C, with a FAD of 0.22 m2/min. The clearance volume is 4% of the swept volume and the stoke/bore ratio is 1.3/1. Take “n” as 1.3, cp = 1.005 kJ/kg K, cv = 0.718 kJ/kg K 1.What is the induced volume per stroke in m3 to 6 decimal places?
Consider a centrifugal pump with curved blades has blade angle at the outlet section equal to 30o, and no shock/no swirl at inlet. Construct the velocity diagrams of this blade at inlet and outlet sections.
In a trial run, the De Laval steam turbine at Oman Power Plant rotates at 3000 rpm. The steam is issued from the nozzle at 400 m/s and the nozzle angle is 20o. The blade speed ratio is 0.41and the friction loss in the blade channel is 15%of the kinetic energy corresponding to the relative velocity at the inlet to the blades. As a turbine engineer at that station, how do you determine the (i) power developed by the turbine for a flow rate of 10 kg/s and (ii) suitable inlet and outlet angles for the blades when axial thrust is zero. Also, how would you determine the size of the turbine wheel required? Draw a suitable velocity diagram.
double sided centrifugal compressor has eye root and tip dia of 18 cm and 30 cm and is to deliver 16 kg/sec air at 16000 rpm. The designed ambient conditions are 15° C and 1 bar and compressor has to be a part of stationary power plant. Determine (1) Suitable value for impeller vane augles of root and tip of eye if the air is given 20° of pre whirl at all radii. Axial component of velocity is constant throughout the impeller and is 150 m/sec. (ii) Max. mach, no. at eye if C,= 1.005 kJ/kg, y=1.4.

= (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. =
