Design a plain surface bearing using the full$-$film hydrodynamically lubricated bearing approach able to carry $1500$lb from a shaft having a diameter of $2\mathrm{.}5$in and rotating at $1000$rpm$.$ Start with a nominal pressure of $240$psi. Identify the required minimum lubricant viscosity, and calculate the friction torque $($lb in$)$ and the frictional power loss $($hp$).$
