Chapter 18, Problem 18.36PP

Figure 18.14 iD shows a two-compartment vessel. The compartments are connected by a smooth convergent nozzle. The left compartment contains propane gas and is maintained at a constant $25.0$ psig and ${65}^{\circ }F$. The right compartment starts at an equal $25.0$ -psig pressure, and then the pressure is decreased to $0.0$ psig. The local atmospheric pressure is $14.28$ psia.

Compute the weight rate of

flow of propane through the $0.5$ -in nozzle as the pressure decreases in $5.0$ -psi decrements. Plot the weight flow rate versus the pressure in the right compartment.
