## Question:

Consider a fluid with mean inlet temperature T_{i} flowing through a tube of diameter D and length L, at a mass flow rate ṁ. The tube is subjected to a surface heat flux that can be expressed as q̇_{s}(x) = a + b sin (xπ/L), where a and b are constants. Determine an expression for the mean temperature of the fluid as a function of the x-coordinate.
