Slope and Deflection

The slope in a deflected beam is described as an angle in radians made by the tangent of the section with the original axis of the beam. The deflection at any point on the axis of the beam is defined as the lateral displacement of the point before and after loading.

enter the heater with an average specific
heat of 1 kJ/kg°C, a mass flow rate of
250 kg/min and an initial temperature of
heat transfer
200°C.
The over-all
coefficient is 75 W/m2°C. Determine the
heating surface in m?.
