Analytic Function for Heat Source in a Pipe

Dear community,
I have a problem with the analytical function. I need to simulate a heat source in a pipe that is not to be distributed evenly.
First I have the function as constant, then linear and plumbed. When I simulated it, I didn't get the performance I expected.
I also don't understand the constant function. The area under the curve in my case must be the power, which is not the case. Also with the linear function, the area under the curve is not the total heat released.
As an example: To distribute 92 W heat (area under the curve = 92 W) over 0.145 m, 634.48 (area of a rectangle = length x width) is required according to simple mathematical rules. Nevertheless, according to Surface Integration, 634.48 W are free. I dont Understand how COMSOL use the analytic function (the handbook dont help me so far).
Thank you for your advices :)
