A 1-m³ rigid tank contains 100 kg R-410a at a temperature of 15◦C, as shown in Fig. P7.116. A valve on top of the tank is opened, and saturated vapor is throttled to ambient pressure, 100 kPa and flows to a collector system. During the process, the temperature inside the tank remains at 15◦C by heat transfer from the 20◦C ambient.

The valve is closed when no more liquid remains inside. Calculate the heat transfer to the tank and total entropy generation in the process.
