Compare the heat loss from an insulated and an uninsulated copper pipe (k =400 W/m K) under the following conditions. The pipe has an internal diameter of 10 cm and an external diameter of 12 cm. The inside surface temperature of the pipe is at 110°C. The pipe is located in a space where all possible outside surface temperature of material was maintained at 30°C. The insulation available to reduce heat losses is 5 cm thick and its conductivity is 0.20 W/m K. If the furnace for heating the fluid in the pipe operating at an efficiency of 85% using natural gas priced at Cg = Php 1.00/MJ, what is the daily cost of heat loss per meter of pipe? And what is the pipe-insulator interface temperature?

Fluid Force. A swimming pool is filled with fresh water to a depth of 7 feet measured at the deep end. There is not enough water in the pool to reach the shallow end. Assume that the pool is constucted using right angles, except where the bottom of the pool meets the end walls. Use Ah for the height of a typical strip across the face of the wall. 6. The weight density of water is 62.4 lb/ Your anwers should have units: pounds. 4 ft 18 ft 24 ft Declare your variable(s) here. Show your reasoning below: a) find the force on the typical horizontal strip (red) ? b) write an integral for the total force on the (left) wall of the pool
