Unit I

1.The dynamic viscosity of an oil, used for lubrication between a shaft and sleeve is 6 poise.The shaft is of dia 0.4m and roates at 190rpm.Calculate the power lost in the bearing for a sleeve length of 90mm.The thickness of the oil film is 1.5mm. 2.Calculate the capillary rise in a glass tube of 2.5mm diameter when immersed vertically in (a)water and (b)mercury.Take surface tension= 0.0725N/m for water and surface tension= 0.52N/m for mercury in contact with air.The specific gravity for mercury is given as 13.6 and angle of contact=130 degree.
