“HOW TO CALCULATE FLOW OF STEAM IN A PIPELINE”
“THERE ARE TWO FORMULAS TO CALCULATE STEAM FLOW IN A PIPELINE”
1. Q (KG/HR) = A (MTR2) X V (MTR/SEC) X DENSITY OF STEAM X 3600
2. Q (KG/HR) = A (MTR2) X V (MTR/SEC) X 3600
SPECIFIC VOLUME OF STEAM
Q= FLOW OF STEAM
A= CROSS SECTION AREA OF PIPE
V= VELOCITY OF STEAM
* SEE DENSITY AND SPECIFIC VOLUME OF STEAM OF PARTICULAR TEMPERATURE FROM STEAM TABLE.
EXAMPLE FOR A CASE OF EXHAUST STEAM OF 120 DEG CENTIGRADE
USING FORMULA NO-1
PARAMETER GIVEN
V=30 METER/SEC
D=1 METER
DENSITY OF 120 DEG EXHAUST=1.13 KG/M3
Q (KG/HR) = A (MTR2) X V (MTR/SEC) X DENSITY OF STEAM X 3600
= 0.785 X 1 X 1 X 30 X 1.13 X 3600
= 95801
EXAMPLE FOR A CASE OF EXHAUST STEAM OF 120 DEG CENTIGRADE
USING FORMULA NO-2
PARAMETER GIVEN
V=30 METER/SEC
D=1 METER
SPECIFIC VOLUME OF 120 DEG EXHAUST=0.885 M3/KG
Q (KG/HR) = A (MTR2) X V (MTR/SEC) X 3600
SPECIFIC VOLUME OF STEAM
= 0.785 X 1 X 1 X 30 X 3600
0.885
= 95797
By above formulas you can calculate flow of steam in a pipeline.
