Given
Diametrical Pitch
where T= no of teeths
D=diameter
module(m) of gears must be same
Let be the gears on two gears
Therefore Center distance is given by
thus
and Velocity ratio is given by
From 1 & 2 we get
Answer:
15300 N
Explanation:
= Density of air at inlet
= Mass flow rate = 60 kg/s
= Inlet velocity = 225 m/s
= Density of gas at outlet =
= Inlet area
= Outlet area =
Since mass flow rate is the same in the inlet and outlet we have
Thrust is given by
The thrust generated is 15300 N.
