From the following data calculate the gyroscopic couple on the bearing in N-m. Mass of disc = 30 Kg, diameter = 60 cm Rotation speed = 1200 rpm Angle between disc and a plane 90 degree to the axis of shaft = 1°

From the following data calculate the gyroscopic couple on the bearing in N-m. Mass of disc = 30 Kg, diameter = 60 cm Rotation speed = 1200 rpm Angle between disc and a plane 90 degree to the axis of shaft = 1° Correct Answer 186

ω = 125.7 rad/s Couple acting on the bearings = mω2r2/8 sin2θ substituting the values we get C = 186 N-m.

A centrifugal pump which circulates a hot liquid metal at 500 degree Celsius is driven by a 3600 rpm electric motor. The motor is coupled to the pump impeller by a horizontal steel shaft of dia 25 mm. Let us assume the motor temperature as 60 degree Celsius with the ambient air at 25 degree Celsius, what length of shaft should be specified between the motor and the pump? It may be presumed that the thermal conductivity of the shaft material is 35W/m K and that the convective film coefficient between the steel shaft and the ambient air is 15.7W/square m K
