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
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
The feed of an ammonia synthesis reactor is 25% (lbmole) nitrogen with the balance hydrogen. The flow rate is 3000 kg/h at 65°C and 95 bar. Calculate the flow rate of nitrogen to the reactor in kg/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 : Calculating adiabatic flame temperature Calculate the adiabatic flame temperature of acetylenes gas at a pressure of 1 bar under the following conditions. The reactants are initially at 298K. Assume that the acetylene reacts completely to form CO2 and H2O: Q : Materials and energy balance you look you look up the specific gravity of 96% H2SO4 and find it is 1.858.calculate the weight

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
A gas contains 350 ppm of H2S in CO2 at 72°F and 1.53 atm pressure. If the gas is liquified, what is the weight fraction H2S?
