A single stage, the single acting compressor has a bore of \(170 \mathrm{~mm}\) and stroke of \(260 \mathrm{~mm}\). it runs at \(130 \mathrm{rpm}\). The suction pressure is 1 bar and delivery pressure is 9 bar. Find the indicated power if compression (i) follows the law pv 1.25 \(=\) constant and (ii) is isothermal. Also, find isothermal efficiency. Assume there is no clearance volume.
