Ethylene is transported through pipelines. It is known that the temperature before the control valve is 15°C and the pressure is 2.7 Mpa; the pressure after the control valve is 1.27 Mpa, with a flow rate of approximately 30 t/h. The diameter of the pipelines before and after the control valve is 8 inches, while the diameter at the control valve itself is 4 inches. How can the temperature after the control valve be calculated? Please provide the calculation process, thank you!
It’s calculated using direct simulation software; manual calculation requires looking up too many things
