the pressure inside a 2 lit container has to be maintained at 0.01 bar. For this purpose, a vacuum pump will be used to pump the air outside. Also, air from atmosphere is leaking back into the container at 1 lit/min. one of the following pumps has to be selected. A. pumps out 10 lit/min B. pumps out 3 lit/min Both the pumps use the same power consumption, both don't need any special cooling process. What other factors will be affecting the pump selection. Which of the above suits best for the purpose? note: this is not a homework question. Hav very little knowledge on Vacuum Technology. Regards.
