In a particular reactor design, a triangular lattice with pitch of 1.2 cm is being used for the reactor. The core is being designed with an 8 mm diameter fuel pellet (uranium nitride, k = 21 W/(m·K)) and a 1 mm thick HT9 steel cladding (k = 18 W/(m·K)). The gap is characterized by a gap conductance of 1300 W/m2K. A choice must be made between designing a sodium-cooled (at 1000 K) or pressurized, water cooled (at 600 K) system. In either case, the flow speed would be 5 m/s and the maximum fuel (centerline) temperature must remain below 2600°C. Find: (a) The maximumlnear heat rate possible for a water-cooled design (in kW/m) (b) The maximum linear heat rate possible for a sodium-cooled design (in kW/m)

Apump is used to circulate hot water in a home heating system. water enters the well-insulated pump operating at steady state at a rate of 0.42 gal/min. the inlet pressure and temperature are 14.7 lbf/in.2, and 180°f, respectively; at the exit the pressure is 60 lbf/in.2 the pump requires 1/15 hp of power input. water can be modeled as an incompressible substance with constant density of 60.58 lb/ft3 and constant specific heat of 1 btu/lb or. neglecting kinetic and potential energy effects, determine the temperature change, in °r, as the water flows through the pump.

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.
