A fan discharges 10,000 cfm of air through a duct 2 ft by 2ft against a static pressure of 0.90 in. of H₂O. The gage fluid density is 62 lbm/ft3 air temp. is 85°F and the barometric pressure is 28.7 in.Hgca). If the power input to the fan is measured as 3.6 Hp, What is the over-all mechanical eff'y of the fan?

|design a simple piston-like crank-slider mechanism that looks similar to the Figure 4 (not to scale). The centre of the crank and the slider are aligned vertically to each other. It has already been determined that the crank radius (O2A) must be 25mm, while the slider block is in a square shape of 20 mm by 20 mm. The highest position of the slider (Hmax), which is the furthest vertical distance of the slider from the centre of the crank, must be 92 mm. Based on the given design parameters, your task is to determine the suitable couple length (AB) and the lowest position of the slider (Hmin). Your superior has asked you to present the results graphically. 20 Slider 10 20 H Crank O2 Figure 4
