Estimate the mass of a piston that can be supported by a gas entrapped under the piston in a 200 mm diameter vertical cylinder when a manometer indicates a difference of 117 mm of Hg column for the gas pressure.
Estimate the mass of a piston that can be supported by a gas entrapped under the piston in a 200 mm diameter vertical cylinder when a manometer indicates a difference of 117 mm of Hg column for the gas pressure.
5. The specific heat capacity of the system during a certain process is given by
cn = (0.4 + 0.004 T ) kJ/kg °C
If the mass of the gas is 6 kg and its temperature changes from 25°C to 125°C find:
(i) Heat transferred;
(ii) Mean specific heat of the gas.
