Passage
Read the passage given below and answer the questions that follows:
In a thermally insulated tube of cross sectional area 4 cm 2 a liquid of thermal expansion coefficient 10 - 3 K - 1 is flowing. Its velocity at the entrance is 0.1 m/s. At the middle of the tube a heater of a power of 10 kW is heating the liquid. The specific heat capacity of the liquid is 1.5 kJ/ (kg K), and its density is 1500 kg/m 3 at the entrance.
