(b) A Freon-turbine has to use a maximum flow rate of $5 \mathrm{~kg} / \mathrm{s}$ of Freon employing a ring of convergent nozzles of total exit area of cross-section of $100 \mathrm{~cm}^{2}$. The pressure in the nozzle entry space is $20 \times 10...
Air is flowing into an insulated duct with a velocity of $150 \mathrm{~m} / \mathrm{s}$. The temperature and pressure at the inlet are $280^{\circ} \mathrm{C}$ and 28 bar respectively. Find the temperature at a section in the duct where the pressure ...
Air flows through a constant area duct with inlet temperature of $20^{\circ} \mathrm{C}$ and inlet Mach number of 0.5 . What is the possible exit stagnation temperature? it is desired to transfer heat such that at exit of the duct the stagnation temp...
