Find the Nusselt number fоr fully develоped flоw (thermаlly аnd hydrodynаmically) between two parallel plates separated by a distance H where both plates receive a constant heat flux q”. Use the hydraulic diameter to calculate Nu in this channel. PLEASE sequentially follow the steps indicated below for a successful development of this lengthy process. Assume slug flow, i.e., u(y) = U, where U is a constant, and calculate the mean velocity um. Draw a control volume of thickness dx between the two plates and perform an energy balance. Indicate the enthalpy in and out and the external heat input. Write the energy balance equation for the control volume by assuming that the fluid is incompressible and obtain an expression for dTm/dx. Write the energy equation and apply the simplifications of fully developed velocity and negligible axial conduction (you don’t have to do a scale analysis). Obtain the dimensionless form of the energy equation for thermally developed conditions, i.e., plug in
