Water is to be boiled at atmospheric pressure in a polished copper pan placed on top of a heating unit. The diameter of the bottom of the pan is 0.2 m. If during 30 minutes the water level is dropped by 0.1 m, calculate the inner surface of the bottom of the pan. Assumptions 1 Steady operating conditions exist. 2 Heat losses from the heater and the pan are negligible 3 The boiling regime is nucleate boiling. Note. Write your answer step by step and clearly explain your work. You need to upload a file.

Question
Water is to be boiled at atmospheric pressure in a polished copper pan placed on top of a
heating unit. The diameter of the bottom of the pan is 00.2 m. If during 30 minutes the water
level is dropped by 0.1 m, calculate the inner surface of the bottom of the pan.
Assumptions 1 Steady operating conditions exist. 2 Heat losses from the heater and the pan
are negligible 3 The boiling regime is nucleate boiling.
Note. Write your answer step by step and clearly explain your work. You need to upload a
