Example.3. A fan of diameter 0.7m running at 1500r.p.m. delivers 140m /min of air at 15°C against 75mm of water of total pressure when its total efficiency is 86 percent. Determine the volume of air delivered, total pressure developed and horsepower consumed, if (a) the air temperature is 50°C, (b) the air temperature is 50°C and the fan speed is increased to 1700r.p.m (c) the conditions are same as in (b) but a 0.6m diameter, geometrically similar fan is used.
