what is the diffrence between mmwc and kg/cm2 for pressure measurment when we are using mmwc and w..

when we r measuring very low pressure :: mmWC
and measuring high pr. :: kg/cm2/bar/psi... ok
for example we r measuring like boiler furnaces
pressure(draft) i.e very low pr.(250mmWC) so we r measuring
in mmWC, and when we r calibrating the transmitters (flow
and level) that time also we r calling transmitters range
also mmWC ok

here note the point is 10,000 mmWC = 1 Kg/cm2 then
1mmwc=0.0001kg/cm2 ok

10000 mmwc equals to 1 kg/cm2.
For low ranges pressure is mentioned in MMWC otherwise in
any other pressure units.

Mostly both are units of pressure. when we measure the very
low pressure than it is expressed in mmwc else higher
pressures are measured in kg/cm2. low pressure can also be
used for but the error in values will be more.
Basically 10000 mmwc is 1 kg/cm2 a.

N/m2 is SI Unit and Kg(f)/cm2 is MKS Unit.

1 Kg/cm2 is 1.033 bar or 1.033x10^5 N/m2
10000 mmwc= 1 kg/cm2

both r units for pressure,.but,mmwc(millimeter water column)is
very low pressure means less than zero.here, 10000mmwc=1kg/cm2.we may consider the mmwc as vaccum.

Basically 10000 mmwc is 1 kg/cm2 a.In thermal power plant mmwc is most useful in boiler side.

To measure low pressure we need to use this unit of
pressure Hence 10000mmwc=1kg/cm2

 Is This Answer Correct ? 16 Yes 3 No

what is the diffrence between mmwc and kg/cm2 for pressure measurment when we are using mmwc and w..

both r units of pressure itself..but when the system is in
vacuum then the pressure measured in mmwc and the positive
pressure measured by kg/cm2.so for low pressure mmwc used
and for high pressure kg/cm2 is used..

MMWC (MILIMETR WATER COLOUM)IS A LOW PRESSURE MEASURING UNIT USE FOR LOW MEASURING AS GAS FLOW ETC AND ONE KG =10,000 MMWC.
MOSTLY USE IT INTO SAMPLE FLOW OF GASES IN ANALYSER AND FLOWMETER AND PREESURE SETTING of pressure switch also.
