The celebrated Lazydog has recently
added a 81 m³ workshop on to his
house. What diameter must a 7 m
long air duct have if the heating and
air conditioning system is to
replenish the air in the room every
19 minutes? The pump can exert a
change in gage pressure of
0.62x10-3 atm. The viscosity of air is
0.018x10-3 Pa.s.
