- 46. A piece of glass has a temperature of 83.0 °C. Liquid that has a temperature of 43.0 °C is poured over the glass, completely covering it, and the temperature at equilibrium is 53.0 °C. The mass of the glass and the liquid is the same. Ignoring the container that holds the glass and liquid and assuming that the heat lost to or gained from the surroundings is negligible, determine the specific heat capacity of the liquid.2. 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?
