Follow these steps to solve:

1) Formulation of the design problem
2) Selection of a conceptual design
3) Initial physical system
4) Modeling of the system
5) Simulation of the system
6) Evaluation of different designs
7) Iteration and obtaining an acceptable design.

Obtain an acceptable design for a cooling system of inner surface of a metallic cylindrical pipe that is at a constant temperature of 360 K by extracting heat in the range of 0.5 to 1 kW from the pipe, using any fluid. The maximum temperature of the cooling medium should be less than 305 K. The ambient temperature is 290 K.
