The steady-state data listed below are claimed for a power cycle operating between hot and cold reservoirs at 1200 k and 400 k, respectively. for each case, evaluate the net power developed by the cycle, in kw, and the thermal efficiency. also in each case apply the equation below on a time-rate basis to determine whether the cycle operates reversibly, operates irreversibly, or is impossible.
a) qh(dot)=600 kw, qc(dot)=400 kw
b) qh(dot)=600 kw, qc(dot)=0 kw
c) qh(dot)=600 kw, qc(dot)=200 kw
equation: integrate (deltaq/t) b = - sigma cycle

Water in a partially filled large tank is to be supplied to the roof top, which is 8 m above the water level in the tank, through a 2.2-cm-internal-diameter pipe by maintaining a constant air pressure of 300 kpa (gage) in the tank. if the head loss in the piping is 2 m of water, determine the discharge rate of the supply of water to the roof top in liters per second.
