Problem

Calculate the power required to compress, up to a pressure of:

5 \mathrm{~kg} / \mathrm{cm}^{2}

a volume of

10 \mathrm{~m}^{3} / \mathrm{h}

of air initially taken at the pressure of 760 mm of Hg and

27^{\circ} \mathrm{C}

, in the following cases: a) When the compression is isothermal. b) When the compression is adiabatic. Take:

\gamma=1,4 \& 1 \text{ atm}=1 \mathrm{~kg} / \mathrm{cm}^{2}
