-URGENT- A closed container with a volume of 2 m3 contains 4 kg of saturated liquid-vapor mixture at 200 kPa pressure. Heat is given from the surrounding environment at 160⁰C until the water in the container is completely saturated vapor. a)Find the entropy change of the system. b) Find the heat transfer to the container. c) Find the total entropy change.

Water at 70°f and streams enter the mixing chamber at the same mass flow rate, determine the temperature and the quality of the exiting stream. 0 psia is heated in a chamber by mixing it with saturated water vapor at 20 psia. if both streams enters the mixing chamber at the same mass flow rate, determine the temperature and the quality of the existing system.

Manometers are good examples of measuring instruments, nowadays they are not as common as before. a)-capacitive probe gauges b)-gravitational gauges deformation ) gauges d)-digital gauges
