Hi there,
I have used an orifice for my project to measure the pressure difference and hence the mass flow rate of air going through a pipe of 26 mm diameter. i kept changing the flow from max to min and ended up with values of pressure diference. The questions here is how to convert thses...
The media is air and it is cooled by water..
I used the energy balance to get the mass flow rate, but I am not convience with the results ..
I am now trying to use squar-edge orifice to calculate the pressure drop and hence the mass flow rate of air, but don't know which one to use ...
that the whole point, i have to do some work to solve this error. I suggested that this is bcoz the mass flow rate which is involved in the calculations is obtained from another experiemental work and it is found by this formula:
m= 4.25/10^3 * SQRT ( pressure drop from inclind mamometer )...
hi ever1,
im final year student doing my final year project at uni. It is basically finding justifications to many abnormal outcomes of the test. I was given 2 standard correlations for Nu and F and these are:
Nu=0.023 Re^-8 *Pr^(1/3)
Fr=0.064/Re^0.2
But when carring out the test I am...
