Name four physical quantities that are conserved and two quantities that are not conserved during a process.

Does the amount of mass entering a control volume have to be equal to the amount of mass leaving during an unsteady-flow process?

Does the amount of mass entering a control volume have to be equal to the amount of mass leaving during an unsteady-flow process?

State what quantities are conserved when balancing a nuclear reaction.

What two quantities must always be conserved in any nuclear equation?

Air enters a 16-cm-diameter pipe steadily at 200 kPa and 20$^\circ{}$C with a velocity of 5 m/s. Air is heated as it flows, and it leaves the pipe at 180 kPa and 40$^\circ{}$C. Determine (a) the volume flow rate of air at the inlet, (b) the mass flow rate of air, and (c) the velocity and volume flow rate at the exit.
