Assuming the energy released by coal as 92OX107 kJ/h, calculate the rate at which heat is rejected from a thermal electric power plant, which produces 1200 MW of power.

In a stainless f‌in (thermal conductivity = 0.18 W/cm°C)of a constant cross-sectional area of 2.5 cm2 and length 1 cm exposed to ambient temperature of 50°C (with a surface heat transfer co-eff‌icient of 0.003W/cm2°C). the temperature distribution is given by (T - T...) = 3x2 - 5x + 6. where T is in °C and x is in cm. Find heat dissipated by the f‌in surface for a base temperature 120°C.

300 KJ/s of heat is supplied to a heat engine at a constant fixed temperature of 230°C. If heat is rejected at 30°C then assuming the cycle as reversible, calculate the amount of heat rejected.

A sharp edged vertical orif‌ice issues a jet of water under a constant head of 0.55 m. The horizontal and vertical co-ordinates measured from the vena-contracta. at a certain point of issuing jet. are 0.512m and 0.09m, respectively. Assuming Cd = 0.7, find the value of CC.
