To upgrade a ventilation system it is required that the air flow rate be increased from 200 m3/min to 300 m3/min. This is to be accomplished by increasing the angular velocity of the ventilation fan. If the current rpm=800, what rpm is required for the upgrade? What will be the power increase for the upgrade?
