An old storage tank of “46” m3 stores steam at 6000 kPa and 330 °C. A crack develops at the
top wall of the tank and steam starts to leak out to the atmosphere. An engineer realizes the
problem on time and stops the leak when the pressure inside the tank is below 4000 kPa. If
the leak is assumed to be adiabatic and reversible,
a) What is the final temperature of the steam remained in the tank? (10 points)
b) How much steam is released to the atmosphere? (10 points)

A 5 m3 tank contains superheated steam at 300°C and 22500 mmHg. The tank (and the steam inside) is cooled until the pressure inside is reduced to 2 bar. At this point, liquid water and saturated steam coexist together in the tank. How much heat was removed from the tank, what is the final temperature, and how many kilograms of steam condensed in the process?

A 10.0 m3 tank contains steam at 250°C and 10.0 bar. The tank and its contents are cooled until the pressure drops to 1.8 bar. Some of the steam condenses in the process. (a) How much heat was transferred from the tank? (b) What is the final temperature of the tank contents? (c) How much steam condensed (kg)?

Thermodynamics A 1 m3 rigid tank has propane at 100 kPa and 300 K. The tank is connected to another 0.5 m3 rigid tank which has propane at 250 kPa and 400 K by a ball valve. The valve is opened and both tanks come to a uniform state at 325 K. 1- State all assumptions you need to solve the problem. 2- Calculate the final pressure of propane in both tanks? 3- Calculate the mass of propane before and after opening the...

An ideal Rankine cycle with regenerative system. Steam enters the turbine at 6000 kPa and 450oC and is condensed in the condenser at 20 kPa. It the steam is extracted from the turbine at 400 kPa to heat the feedwater in an open feedwater heater and the water leaves the feedwater heater as a saturated liquid. Find the rate of heat added in the boiler? Find the rate of heat rejected in the condenser? Determine the network output per kilogram...

A 1.0 m3 tank, initially filled with 103. kPa, 300. K air, is connected to a source of air at 1,500. kPa, 300. K. The tank slowly fills until it is at the same pressure. If the temperature is maintained at 300. K throughout this transient process, what is the total heat transfer required? (You can assume air is an ideal gas.)
