2. Drive an expression for the volumetric efficiency of reciprocating air compressors

3. Explain the construction and working of a root blower ME8493 Important 16 Mark Questions Thermal Engineering 1

4. Explain the construction and working of a centrifugal compressor

5. Explain the construction and working of a sliding vane compressor and axial flow compressor.

6. A single stage single acting air compressor is used to compress air from 1 bar and 22° C to 6 bar according to the law PV1 .25 = C. The compressor runs at 125 rpm and the ratio of stroke length to bore of a cylinder is 1.5. If the power required by the compressor is 20 kW, determine the size of the cylinder.

7. A single stage single acting air compressor is used to compress air from 1.013 bar and 25° C to 7 bar according to law PV 1.3 = C.The bore and stroke of a cylinder are 120mm and 150mm respectively. The compressor runs at 250 rpm .If clearance volume of the cylinder is 5% of stroke volume and the mechanical efficiency of the compressor is 85%, determine volumetric efficiency, power, and mass of air delivered per minute.
