Hi all,
If I only know the Pressure given by a known Force on the barrel side of the syringe, the Density of the fluid, the Cross Section Area of the two parts of the syringe, the length of the syringe barrel and a ball with known Mass being pushed by the fluid flowing out of the syringe...
I'm doing a lab on Laminar Flow Elements - Fan Performance Test.
So far I have had to find power coefficients (CP), discharge coefficient (CQ) and head coefficients (CH). I've plotted CH vs. CQ, CP vs. CQ and Efficiency vs. CQ.
My last requirement is that I "Use the curve fits to...
Hi; Could someone please help me with this question: "Suppose you have measured the flow rate for a number of tubes with different lengths but the same radius, how would you graph your data to test Poiseulle's law (Hint: choose the scales of the axes so that the theoretical graph is a straight...
Is the overall flow rate through a closed loop with a pump constant? I've always though that if a pump can do a specific amount of work, it doesn't matter if the 'loop' of tubing goes up and down, or what types of turns it takes. I've thought this because if the tubing goes down then up (or...
If subsonic flow is accelerated in a converging duct to mach 1 and then the duct is further converged, choked flow will occur. Will flow at the exit of the duct be compressed as the volume flow rate is decreasing but the mass flow rate has to remain the same.
Hi all.
Suppose I am increasing the flow rate of the water through a sprinkler or a tube, there should be some vibration induced by this increment of flow rate, right?
On the other hand, if I decrease the flow rate of the water through the same sprinker, there should also be vibration induced...
hey,
Can anybody suggest a method of measuring very small flow rates of a few ml per hour precisely.This is a diffusion experiment where water is allowed to pass through a membrane at a constant pressure.we have to know the amount of water passing through the membrane.There will not be any...
hi ,
I have a question that if you answer it I would be so thankfull, Q is:
"Can we calculate volumetric flow rate without knowing cross-sectional area?
If,yes,How?"
I have this Q because I see a portable Thermometer,volumetric flow rate meter ,which show it without giving any area size...
Hi! This is the first question on my homework, so it's suppost to be the easiest, but I'm not sure how to tackle it. It's a Bernoulli's principle problem. Here it is:
A horizontal pipe 11.6 cm in diameter has a smooth reduction to a pipe 4.72 cm in diameter. If the pressure of the water...
For a physics project I've decided to investigate factors affecting the flow rate of liquids. One of the factors I'm investigating is how an increase in liquid in a container will induce greater pressure and hence increase the flow rate. I need a theoretical link for the data I obtain for this...
My statistical dynamics and other useful areas of physics was sorely lacking in my undergrad education. Take this for instance, at work I need to calculate the gas flow rate from a tube into a very large chamber. I know the diameter of the tube and pressures of the gas.
Bernoulli's equation...
By Bernoulli's law, if potential energy is constant, the work done, given by pV, where p is the pressure, V is the change in volume, is equal to the change in kinetic energy, 1/2mv^2.
Does that mean that the flow rate of the liquid is proportionate to the root of the pressure applied??
If...
Trying to convert differential pressure (inch WC) measurements from a 6-inch diameter pipe into an air flow rate (cfm).
Here's what I got so far...
I'm assuming laminar, imcompressible flow with negligible friction, head, or thermal losses (this is a very low-flow system). From the...
Two parallel thin metallic plates with a gap between them are used as a heat insulator. How does the heat flow rate through this device depend on the temperatures on its two sides in the following two cases?
Case 1: The gap is filled with air.
Case 2: There is a vacuum in the gap.
