PROBLEM SET 5
1. The specific weight of water at ordinary pressure and temperature is 62.4 lb/ft (9.81 kN/m³).
The specific gravity of mercury is 13.55. Compute the density of water and the specific weight
and density of mercury.
2. One cubic foot of oxygen at 100'F and 15 psia is compressed adiabatically to 0.4 ft. What then,
are the temperature and pressure of the gas. If the process had been isothermal, what would
the temperature and pressure have been?
