Advanced Energy Systems at Steady StateRefrigerant 134a
Chapter 4, Problem 99P(choose chapter or problem)
Refrigerant 134a enters the flash chamber operating at steady state shown in Fig. P4.99 at 10 bar, \(36^{\circ} \mathrm{C}\), with a mass flow rate of 482 kg/h. Saturated liquid and saturated vapor exit as separate streams, each at pressure p. Heat transfer to
the surroundings and kinetic and potential energy effects can be ignored.
(a) Determine the mass flow rates of the exiting streams, each in kg/h, if p = 4 bar.
(b) Plot the mass flow rates of the exiting streams, each in kg/h, versus p ranging from 1 to 9 bar.

QUESTION:
Refrigerant 134a enters the flash chamber operating at steady state shown in Fig. P4.99 at 10 bar, \(36^{\circ} \mathrm{C}\), with a mass flow rate of 482 kg/h. Saturated liquid and saturated vapor exit as separate streams, each at pressure p. Heat transfer to

(a) Determine the mass flow rates of the exiting streams, each in kg/h, if p = 4 bar.
(b) Plot the mass flow rates of the exiting streams, each in kg/h, versus p ranging from 1 to 9 bar.
ANSWER:Step 1 of 4
First we have to calculate the mass flow rate and we need to plot the graph p versus .
