23. If pressure driving the sample stream in a flow cytometer is increased, how will the diameter of the sample stream at the interrogation point change? explain briefly
Homework Answers
The sample pressure regulator controls the diameter of the sample stream at the interrogation point change.
At low pressure, the cells of the sample travel from the interrogation point one at a time. Due to the increasing pressure the thickness of the core stream and the flow speed of the cells from the interrogation point increase. This results in the flow of more than one cell to bypass by the laser at a particular time which results in the assortment of coincident events.
The sheath fluid is derived through the flow chamber by the pressure of air supplied by the compressor. The exact pressure is applied to force the sample onto the sheath. The sample flow rate is regulated by the pressure regulator.

Example You are studying pressurized flow of an aqueous solution in a cylindrical tube with pressure difference of 10 Pa between the inlet and outlet. . 1) Under steady state condition, sketch the velocity profile. 2) If the tube diameter decreases to 1/3 of the original diameter, how would the flow rate change? If the pressure difference increases to 20 Pa, how would the flow rate change? 3)

Consider a stream of water falling freely at atmospheric pressure from an open faucet. At the exit of the faucet the stream has a diameter of 15 mm. The stream is laminar at all times and has a circular cross section. You also measure that the stream fills a 2.5 liter bucket in 35 seconds. The density of water is 1.0 kg/liter. Part a: Calculate the flow rate. Part b: Calculate the current. Part c: Find the velocity of the...
