A rigid tank that contains 2 kg of N2 at 25=C and 550 kPa is connected to another rigid tank that contains 4 kg of 02 at25°C and 150 kPa- The valve connecting the two tanks is opened, and the two gases are allowed to mix If the final mixturetemperature is 25°C, determine the volume of each tank and the final mixture pressure. Note:A figure is drawn in which two cylinders are shown and connected to each other

The y form of iron is known as: a) ferrite b) cementite c) perlite d) austenite

Apump is used to circulate hot water in a home heating system. water enters the well-insulated pump operating at steady state at a rate of 0.42 gal/min. the inlet pressure and temperature are 14.7 lbf/in.2, and 180°f, respectively; at the exit the pressure is 60 lbf/in.2 the pump requires 1/15 hp of power input. water can be modeled as an incompressible substance with constant density of 60.58 lb/ft3 and constant specific heat of 1 btu/lb or. neglecting kinetic and potential energy effects, determine the temperature change, in °r, as the water flows through the pump.

Most leaks in reciprocating air compressors can be detected and minimized by: (clo4) a)-detecting leakage areas using ultrasonic acoustic detector. b)-tightening joints and connections c)-replacing faulty equipment d)-all of the given options
