In the interests of fuel economy on a Diesel powered big-rig, an engineering goal of reducing the viscous fluid forces by 50% on a main engine bearing has been set.

The initial bearing viscous fluid force was 4.5 N. You need to find a new oil viscosity which will enable this force to be lowered to 3 N. So....If the bearing has an area of 15 cm? , and is supported by a 10 µm thick oil film, and the bearing speed is 5 m/s find the viscosity (in units of Pa*s) needed for a bearing viscous fluid force of 3 N.M6_M9_EASC_2213_02_Quiz_201112.pptx
