An angular-contact, inner ring rotating, 02-series ball bearing is required for an application in which the life requirement is 37 kh at 540 rev/min. The design radial load is 725 lbf. The application factor is 1.4. The reliability goal is 0.93. For a C10 value of 63.7 kN, what is the reliability using the design factor, force, speed, and desired life from part a? The reliability is:.

A2-m rigid tank initially contains saturated water vapor at 100 kpa. the tank is connected to a supply line through a valve. steam is flowing in the supply line at 600 kpa and 300 c. the valve is opened, and steam is allowed to enter the tank until the pressure in the tank reaches the line pressure, at which point the valve is closed. a thermometer placed in the tank indicates that the temperature at the final state is 200°c. determine (a) the mass of steam that has entered the tank (b) the amount of heat transfer.
