The furnace is constructed with 20cm of brick where the k=1.36W/m°K, 10cm insulating brick with k=0.26W/m°K and 20cm of building brick with the k=0.69W/m°K. The inside surface temperature is 650°C. The heat losts from the furnace wall is 56W/m square. Determine a). The interface temperatures and the outside wall temperatures.​

Water is siphoned from a large tank and discharges into the atmosphere through a 50-mm diameter tube. the end of the tube is b = 2.1 m below the tank bottom which is a = 7.4 m deep, and viscous effects are negligible. determine the maximum height h over which the water can be siphoned without cavitation occurring. atmospheric pressure is 101.4 kpa, and the water vapor pressure is 1.79 kpa (absolute)
