write a program that will calculate the heat transfer of a substance (water) given three different shapes. The user has to be able to input the type of shape, so that the computer can calculate area, and plug it back in to the equation for heat transfer. The equation for heat transfer is given as:
q = (h)*(A)*(Ts-Ta)
q= heat transfer
A = area of the user inputted shape
Ts= surface tempurature
Ta= ambient tempurature
h= convective heat transfer coeeficient (given as 8.7 W/(C*m^2)
The three different shapes that have to be calculated for area (user choice) are:
1-A rectangular area
2-An elliptical area
3- Other area
The equation for an elliptical area is given as pi*(little radius)*(big radius)
For 'other' area, the user just imputs the area.
Here is my program so far. Could you please tell me what I'm doing wrong? I'm getting a ton of error messages.
