Question

A two stage single acting air compressor delivers, 1000 kg/hr of air at 20 bar pressure. The suction occurs at STP conditions . Assume the process to be ideal; the free air delivery is _____ $m^{3} / m i n$
12.89

Open in App

Solution

The correct option is A 12.89
$m = 1000 k g / h r$

$R = 0.287 k J / k g K = 287 J / k g K$

STP conditions

$P = 101.325 k P a$

$T = 273.15 K$

$∴ Free air delivery, V = \frac{m R T}{P} = \frac{1000 \times 387 ⊓ 273.15}{101.32 \times 10^{3}} = 773.72 m^{3} / h r = 12.89 m^{3} / m i n$
