Finding Frictional Pressure Drop in a Gas system through Simscape object Pipe(G)

I aim to find out the pressure drop in a gas flow due to friction through the Pipe (G) object. I have given the following Parameters for the Pipe(G) object:
Length = 50 m
Cross-sectional Area = 10 m^2
Hydraulic Dia = 3 m

I have connected the Temperature and Pressure Sensor (G) but it is simply displaying a result equal to the Pressure difference between the two reservoir. Which isn't I require. Please provide a suitable solution.
Thank you very much in advance!

Hi Abhishek,
From my understanding, you are trying to find the pressure difference caused by pipe due to friction.
This is an expected behaviour. The pressure of the gas entering and leaving the reservoir will be same. So, the Temperature and Pressure sensor will sense the pressure difference between the reservoirs as output.
For more information refer the documentation below:
Hope this helps.

The mass flow rate plays a major role in causing pressure difference due to friction in pipe.
Although the other parameters can be changed in pipe but for mass flow rate, we need to add Mass Flow Rate (G) block. For more information, please refer to the links below:

Hope this helps!
