Assuming that there are two different systems 1 and 2, system 1 and 2 interact through a small hole. If system 2 pressure is higher, we ask if there is a hydrodynamic formula or other scientific formula that explains how the gas flow is in the hole.
[For example, the flow of gas when a small hole is formed in a sealed bag containing air]
※ The gas in system 1 and 2 is air.
solids tomato purée as it fl ows through a steam injection
heater at a rate of 400 kg/h. The steam is generated at
169.06 kPa and is fl owing to the heater at a rate of 50 kg/h. If
the specifi c heat of the product is 3.2 kJ/(kg K), determine the
temperature of the product leaving the heater when the initial
temperature is 50°C. Determine the total solids content of the
product after heating. Assume the specifi c heat of the heated
purée is 3.5 kJ/(kg°C).
stream of O2. The final stream composition is 2.05 mole % methane. Determine the amount
of O2 needed to dilute the feed stream.
Hint: Assuming a basis may be helpful
a. Find the conversion.
b. Compare this conversion with what you will get if there is no recycle.
