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. How much bigger is the volume rate of flow at the end of the tube than at the entrance in cubic meters?

Options

A. `9xx10^(-5)`
B. `1/3xx10^(-5)`
C. `4/9xx10^(-5)`
D. None of these

Answer

C
