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
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 as

Modeling eye movements is commonly performed in the Matlab/Simulink pacakage. Based on the Physiological evidence, oculomotor plants have been designed to simulate various eye movements. Choose two eye movement models, one for saccades and the other for pursuit, and simulate the following amplitudes
A heater (heat source temperature = 527 K) and turbine are connected in series as shown below: Q : Problem on laboratory solution You are You are asked to make up a laboratory solution of 0.10 molar H2SO4 from concentrated (96%) H2SO4 at 56°F.
