#initialisation of variables
V1=1.0      #volume
p2=2000     #pressure lbf/in^2
p1=1000     #pressure lbf/in^2
K=350000    #k factor lbf/in^2

#CALCULATIONS
dV=V1*(p2-p1)/K

#RESULTS
print('The fluid be expected compress is = %.4f ' %dV)

The fluid be expected compress is = 0.0029

In [1]:
import math

#CALCULATIONS
m1=36815.0    #Particles count upstream
m2=6347       #Particles count downstream
b=m1/m2       #beta ratio

#RESULTS
print('The beta ratio = %.1f ' %b)

The beta ratio = 5.8

In [2]:
import math


#CALCULATIONS
m1=36815.0     # Particles count upstream
m2=6347        #Particles count downstream
b=((m1-m2)/m1)*100    # Beta efficiency

#RESULTS
print('The beta efficiency = %.2f percent' %b)

The beta efficiency = 82.76 percent
