For the cases below, a closed system undergoes a process in which work is done on the system and the heat transfer Q occurs only at a location on the boundary where the temperature is Tb. For each case, determine whether the entropy change of the system is positive, negative, zero, or indeterminat. a. internally reversible process, Q > 0.b. internally reversible process, Q = 0.c. internally reversible process, Q < 0.d. internal irreversibilities present, Q > 0.e. internal irreversibilities present, Q = 0.f. internal irreversibilities present, Q < 0.

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.
