II. In the normal operating conditions, cylinder air compressor inlet and outlet conditions are given in Table 1 below. Cooling water in the compressor jackets absorbs heat from the air at the rate of 60 kW. Use steady flow energy equation (SFEE) to compute the rate of shaft work input to the air in kW and find the required ratio of the inlet pipe diameter to outlet pipe diameter. Parameter Air inlet conditions Air outlet condition Velocity (m/s) 8 6 Mass flow rate (kg/s) 0.5 - Pressure (kPa) 101 680 Specific volume 0.95 0.19 ($m^3$/kg) Internal Energy (kJ/kg) 320 390 Table 1: Compressor air inlet and outlet conditions

3. Determine the resistance of a bar of n-type silicon at room temperature (300°K). The length of the bar is 10 cm and its radius is 20 mm. Silicon: $\mu_n$ = 0.135 m$^2$/V-sec, $\mu_p$ = 0.048 m$^2$/V-sec, $n_i$ = 1.5 x10$^{10}$/cm$^3$, atomic weight = 28.09, density = 2.33 x 10$^6$ g/m$^3$, T= 300°K. $N_D$=5 x10$^{20}$ As atoms/m$^3$ Hint: Convert cm units to m units in the intrinsic carrier density $n_i$ given above.
