I am attaching both questions for 4 and 5 with the question in the image. thank you. NOTE : So the last person answered this question WITHOUT refencing the answer for whether question 4 or 5 answeres were given, so i am asking for question 5(or the answer for the question that was NOT solved because it was not referenced.) These were the following answers given to me from the last person on bartleby who answered my question without referencing whether it was the answer for question 4 or 5. 1 pass 2 fail 3 fail 4 pass
A fan delivers 283.2 m³ / min of air with a density of 1.2 kg/m³ through a duct 5.08 cm by 5.08 cm at the static pressure of 2.3 cm WG. If the power input to the fan is measured as 2.70 kW, determine; (a) the air velocity, m/sec (b) the total head if the velocity head is 8.2 meters (c) the mechanical efficiency of the fan.
