Experiment $1$ TWO STAGE COMPRESSOR

AIM:

To determine the actual air flow rate, swept volume, electrical horsepower, isentropic horsepower, isothermal horsepower, isentropic efficiency, isothermal efficiency and volumetric efficiency.

APPARATUS:

Note: Motor: Hascon $220$V$,50$Hz$,3$HP$,2\mathrm{.}2$ KW$,8\mathrm{.}91$A$,1430$RPM

Air compressor: $1^{st}$ stage SB$-10/90$ bore $65$ mm $,$ stroke $44$ mm $($twin cylinders, $90$ degree phase shift$)$

$2^{nd}$ stage SA$-1/36$ bore $51$ mm $,$ stroke $42$ mm $.$

TDY$2602$

DATA SHEET:

Air box orifice... $1\mathrm{.}5mm.mm,$ Atmospheric pressure, $P_u=$ lar $q,$ mm

Note: Motor: H

TDY$2602$

INSTRUCTIONS:

Calculate: $$

Actual air flow rate $(q)$

Swept volume, from the size of the cylinder and stroke of the piston in stage $1$ and speed.

Electrical horsepower $($EP$),$ by installing a wattmeter on the motor.

Isentropic horsepower $($isen$.$ HP$).$

Isothermal horsepower $($iso$.$ HP$).$

Isentropic Efficiency $($Isen$.$ Eff$)$

Isothermal efficiency $($Iso Eff$).$

Volumetric efficiency $(V$ ol Eff$).$
