So here in this question basically we are given a gas which is flowing through a long pipe with the constant diameter and we are given its diameter of the pipe that is equals to the constant and the outlet of pipe is lower than that of the inlet.
00:20
So gas is at constant temperature throughout the point.
00:24
So here in the first part we can say that we have to determine about the mass flow rate at the inlet and the outlet.
00:34
So from here we can say that the mass flow rate from here since the system is at the steady state.
00:44
So we can say that the mass flow rate at the inlet is equals to the mass flow rate at outlet.
01:05
So this is because that the mass which is entering the pipe let's say this from here is the pipe.
01:14
So here this is the mass which is entering in the pipe must be equals to the mass which is leaving from the pipe as there is no accumulation of mass within the pipe hence the answer to the part one.
01:25
For the part two we are considering about the densities of the inlet and the outlet.
01:32
So we can say that as the gas is an ideal gas and the temperature from here remains constant throughout the pipe.
01:40
So the ideal gas equation is pv is equals to nrt.
01:45
So since the outlet pressure is higher as compared to inlet p.
01:56
So we can say that the density of the gas since the pressure is higher and the t is constant.
02:05
So we can say that the density of the gas at the outlet must be equal must be higher higher than that of the inlet density and inlet.
02:30
So this is the answer to the part two.
02:32
For the part three we are considering about the volumetric flow rate.
02:38
So from here from the volumetric flow rate we can say that the volumetric flow rate is given by the mass flow rate divided by the density.
02:49
So vfr is representing the volumetric flow rate that is equals to mass flow rate divided by the density...
