Problem 3 An air-cooled condenser is to reject 70 kW of refrigerant to air. The condenser has an air-side area of 210 m² and a U value based on this area of 0.037 kW/m²-K; it is supplied with 6.6 m³/s of air which has a density of 1.15 kg/m³. If the condensing temperature is to be limited to 55°C, what is the maximum allowable temperature of the inlet air? heat from condensing a th = constant O(= th – te) 1 2

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.
