A square isothermal chip is of width w 5 mm on a side and is mounted in a substrate such that its side and back surfaces are wel
l insulated, while the front surface is exposed to the flow of a coolant at To 15°C. From reliability considerations, the chip temperature must not exceed T 85°C. Coolant T, h Chip If the coolant is air and the corresponding convection 200 W/m2 K, what is the maximum coefficient is h allowable chip power? If the coolant is a dielectric liq- uid for which h 3000 W/m2 K, what is the maxi- mum allowable power?

Answer:
The final temperature of water is 381.39 °C.
Explanation:
Given that
Mass of water = 5 kg
Heat transfer at constant pressure Q = 2960 KJ
Initial temperature = 240 °C
We know that heat transfer at constant pressure given as follows
We know that for water
Lets take final temperature of water is T
So
T=381.39 °C
So the final temperature of water is 381.39 °C.
