The 0.5 m x 1.2 m wall of an industrial furnace is constructed from L = 0.15-m-thick fireclay brick having a thermal conductivity of 1.7 W/m-K. The temperature distribution, at an instant in time, is T(x) = a + bxwhere a = 1400 K and b = -1050 K/m. Determine the heat fluxes, q, and heat rates, q,, at x = 0 and x = L, in W/m2 and W respectively. Do steady-state conditions exist? W/m2 1x=0 i W/m? i W Ix=0 = Ir=L = i W Steady-state conditions exist.

I need help on this question: (This question requires the use of Roger & Mayhew Steam Property Tables) Saturated steam at 1 atm is condensed on the external surface of a copper tube withan outside diameter 16 mm and tube wall of thickness 0.5 mm. The tube is cooledinternally by water with a mass flow rate of 0.06 kg/s, which in turn is raised intemperature from 15 oC to 60 oC as it flows through the tube. (Take the heat-transfer coefficient at the condensing side as 10.0 kW/m2K and the isobaric specific heat-capacity of water as 4180 J/kg K.) a) To calculate the heat transfer rate to the cooling water b) To calculate the length of the tube c) Comment on how to enhance heat transfer in this case.
