A Boeing 777 landed at Chicago O’Hare Airport (668 m elevation) where the pressure is 98.8 kPa. Assume that the landing speed is 196.4 mi/hr. This 777 wing has a coefficient of drag of 0.034 and its wing area is 429.1 m2. What is the drag at the point where the aircraft just lands on the ground? Note that these conditions are non-standard so use altitude to calculate temperature then use the pressure given to calculate density.

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.

What is the main objective of using reheat rankine cycle?

The process in which the system pressure remain constant is called a)-isobaric b)-isochoric c)-isolated d)-isothermal
