Problem on flow rate of natural gas
Natural Gas is flowing through a 10 inch schedule 40 pipe. The gas is at 109°F and 7.3 psig. The outside air temperature is 92°F. If the flow rate of the gas is 8,000 SCFM: What is the flow rate in lb/hr?

The cross sectional Area of the Pipe
= (22/7)*((power(10.75,2)-power(10.02,2))= 47.65231429*0.00694444444=0.330918849sq ft
Now the volumetric flow rate 8000 SCFM means 8000 cubic ft
PV=nRT
P=7.3 psig=7.3+14.7 psi =22psi=22*6894.75729 pa
=151684.6604Pa
V=8000 cuft V=8000*0.0283168466 cubic meters=226.5347728 Cu m
Temp =306.4833K
N= 151684.6604Pa*226.5347728 Cu m/(8.314J/K-mole*306.4833K)= 13485.27177 mole
Considering the Nutral gas is methane CH4 =16kg/mole
So Mass flow rate =215764.3484Kg/Hr =475678.9634lb/hr
A stream of propane is throttled from 4.298 bar and 450 K to 0.22 bar. This process is irreversible due to frictional losses at the nozzle. a. In words or equations, why are frictional losses irreversible? Q : Problem on entropy A heater (heat A heater (heat source temperature = 527 K) and turbine are connected in series as shown below: Q : Temprature To determine the temperature To determine the temperature that occurred in a ?re in a warehouse, the arson investigator noticed that the relief valve on a methane storage tank had popped open at 3000 psig, the rated value. Before the ?re started, the tank was presumably at ambient conditions and the gage read 1950 psig. If

I) Sulphur dioxide (SO2) with a volumetric flow rate 5000cm3/s at 1 bar and 1000C is mixed with a second SO2 stream flowing at 2500cm3/s at 2 bar and 200C. The process occurs at steady state. You may assume ideal gas behaviour. For SO2 take the heat capacity at constant pressure to be CP/R = 3.267+5
