In a thermally insulated tube of cross sectional area `4cm^(2)` a liquid of thermal expansion coefficeint `10^(3)K^(-1)` is flowing. Its velocity at the entrance is `0.1m//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 `1500kg//m^(3)` at the entrance.   Q. What is the density of liquid at the exit?
