Packager and Parts Distributor Support Data. Visit page. Supply line, Piston — moves through the cylinder in a reciprocating action to compress the gas. Intake valve — to let the air to drawn into the cylinder. Outlet valve — to let air out of the cylinder. Crank shaft — connect to the motor to provide the rotary motion.

Connecting rod — connect the crank and the piston — provide the reciprocating ups and down movement. Assume the compression process being polytropic and the polytropic index is 1. Calculate: a mass of air delivered per minute, and b indicated power. Question 3. Calculate the indicated power required for a free air delivery of 0.

If the compressor is single-acting and has a stroke to bore ratio of 1. If polytropic index is 1. The FAD is 0. The clearance ratio is 0. The expansion 32 process of the cycle follows the law of pV1. For this purpose the induction and free air conditions can be taken as 1. Calculate: a the bore and stroke b the volumetric efficiency c the indicated power d the isothermal efficiency Take the index of compression and re-expansion as 1.

Taking the bore as calculated in Question 3. Calculate also the volumetric efficiency and compare it with that of Question 3.

Answers: 0. It will be brought back to its inlet temperature before induction process. Indicted Mean Effectiv e Pressure. We know that isothermal work done. A two stages, single acting air compressor compresses air to 20bar. The air enters the L. P cylinder at 1bar and 27 o c and leaves it at 4.

The air enters the H. P cylind er is mm diameter and mm stroke. The compressor runs at rpm, taking index of compression and ex pansion in the two cylinders as 1. The indicated power required to run the comp ressor; and 2. The heat rejected in the intercooler per minute.

Indicated power required to run the compressor. We know the sw ept volume of the L. P cylinder.
