Question 34
CHNAT2 marksNeeds review
An insulated storage tank contains 1000 kg liquid of specific heat 10 kJ kg⁻¹ K⁻¹. The liquid is heated by saturated steam, condensing in a helical coil at a temperature of 180 °C. The heat transfer area of the coil is 0.1 m². If the overall heat transfer coefficient is constant at 1000 W m⁻² K⁻¹, then the time (in hours) required to raise the temperature of the liquid in the tank from 20 °C to 80 °C is __________ (rounded off to second decimal place).
