    Engineering Calculate valve sizing to regulate the flow of natural gas

    Working out as follows x= (20-6)/20 = 0.7 Fk = k / air specific heat ratio Fk = 1.31/1.4 Fk = 0.94 xT = Fk * x 0.94 x 0.7 = 0.658 because xT < x = 0.658<0.7 flow through the valve is choked Expansion factor Y Y = 1 - x/( 3 x Fk x xT ) Y= 1- 0.7/( 3 x 0.94 x 0.658) Y = 0.623...

    How Do You Calculate Choked Flow of Propane Based on Natural Gas Parameters?

    hello, did you ever figure out if either the 6.7litre/s or 8.03litre/s is correct? I am at exactly the same point as you and unsure which value to use

    Engineering Calculate the max common mode voltage at the differential amplifier inputs

    Im unsure if I am on the correct track or have gone off on a tangent. Any help or guidance would be appreciated. CMRR=20log10(Adiff/Acm) 120=20log10(10^5/Acm) 120/20=log10(100,000/Acm) 6=log10(100,000/Acm) taking antilogs 1,000,000=100,000/Acm Acm=100,000/1,000,000 Acm=0.1Max amplified...
