Crude oil is transported from a storage to a refinery through a 10 schedule 40 pipeline which is buried 1.5 m below the ground surface. In a cold winter day the air temperature is 10 C and the ground surface temperature is 2 C. The thermal conductivity coefficient of dirt is 0.8 W/mC. How much heat (in kW) will be lost from 1 km long pipeline if the temperature of crude oil is kept at 20 C?
