In a thermal power plant, a horizontal copper pipe of "D" diameter, "L" length and thickness 1.9 cm enters into the boiler that has the thermal conductivity as 0.37 W/mk. The boiler is maintained at 102 °C and temperature of the water that flows inside the pipe is at 34°C. If the energy transfer (Q) is 100735 kJ in 7 hours. Determine the Heat transfer rate, Surface area of the pipe and Diameter & Length of the pipe, if D = 0.015 L.

Question
In a thermal power plant, a horizontal copper pipe of "D" diameter, "L" length and thickness 1.9 cm
enters into the boiler that has the thermal conductivity as 0.37 W/mK. The boiler is maintained at 102
°C and temperature of the water that flows inside the pipe is at 34°C. If the energy transfer (Q) is
100735 kJ in 7 hours.
Determine the Heat transfer rate, Surface area of the pipe and Diameter & Length of the pipe, if D =
0.015 L.
