A hydraulic system uses an input and output piston cylinder with 3000 psi. The input piston has an area of 3.14 in2 and needs a force of 9420 lbs. The output piston has an area of 19.6 n2. How much force does the second (output) piston cylinder apply? What is the mechanical advantage of this system?

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.
