My question: A process pump has a pumping speed (S) of 1000 L/min, independent of the inlet pressure. This pump is connected to a process chamber through 10 m of tubing that is 2 cm in diameter. If the desired chamber pressure is 2 torr, calculate the maximum gas throughput that can be introduced into the chamber in standard liters per minute. Here is a reference Q&A but i need steps Reference Question: A process pump has a pumping speed (S) of 2000 L/min, independent of inlet pressure.This pump is connected to a process chamber through 10 m of tubing that is 5 cm indiameter. If the desired chamber pressure is 1.0 torr, calculate the maximum gas throughputthat can be introduced into the chamber in standard liters per minute. (Hint: Recall thatQ =P *S.) Reference Answer:

10.10) For this problem, the inlet pressure is unknown, so 2 242 Pchamber = Pinlet CS C Then, 33 This document is available free of charge on studocu Do. ."bauer chamber 1 1 S Putting in the correct values, 2 C=1.8 *105 tory- sec-1 (5cm) 4 Pchamber + S - =3375 L 300cm 2 = K Pchamber + 6 /10 torr - min Pchamber + Inserting this last form into the previous equation and doing a bit of algebra, Q2 + . K -2 - Pchamber2 $2 = 0 Solving the quadratic, Q=1.96 slm. One can verify, Pinlet=Q/S=0.75 torr, and Q/C = 0.25 torr
