gaseous state
a monometer is connected to a gas containing bulb. The open arm reads 43.7cm where as the arm connected to the bulb reads 15.6cm. if the barometric pressure is 743mm of mercury. what is the pressure of gas in bar?

Note for OP
+solved @user1 @user2... to close the thread when your doubt is solved. Mention the users who helped you solve the doubt. This will be added to their stats.Pressure of bulb = P of air + reading of open arm
Can you explain the basis of this pls. I did study monometer but not in too deep.
I don't get how there's a reading in both the arms
@hardcoreisdead
same water levl pr same pressure? Ye to samjh gye na @hardcoreisdead
I perceived this since there were two different values at each diff arm
yes shi h
Then how do we infer pressure from this
Dono side se kuch kuch aa rha haj
Find the pressure at the bottom of this
Find the pressure at the bottom of this (assume pressure of gas=x)
Pressure of the liquid at the bottom is the same since they are located at the same depth
Pressure of gas from this part alone is 76+43.7?
You need to use rho x h x g
for the liquid part
