A manometer is fastened to a pipe to measure the velocity of SAE (30) oil as it flows at steady state. The manometer is designed to read the static and stagnation pressures of the flow and uses water as the gage fluid. Determine the upstream velocity V of the oil.

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.
