1
Velocity of flash vapour in flash tank
Author:
Umax = C x [ (ρ L – ρV)/ ρV]0.5

Flash vapour Quantity
Author:
[ M x Cp x (Ti-To)]/ λ
Its comes in T/hr than it is to be converted into M3/sec by using specific volume of vapour

Flash Tank Juice inlet Dia
Author:
By using general formula Q = AV ( V = juice inlet velocity and Q = Qty of juice inlet)
mm
Say
mm
4
Flash tank Dia
Author:
By using general formula Q = AV ( V = Velocity of flash vapour in flash tank and Q = Qty of flash vapour)
mm
Say
mm
5
Flash tank Vapour Vent Pipe Dia
Author:
By using general formula Q = AV ( V = flash vapour velocity in vent pipe and Q = Qty of flash vapour)
mm
Say
mm
6
Flash tank juice outlet Dia
Author:
Q = AV ( Q= Qty of juice and V = Velocity of juice outlet) or can be calculate
D > 1.116 (Q)0.4
mm
By D > 1.116 (Q)
^{0.4}
mm
By Q = AV
Say
