🤓 Based on our data, we think this question is relevant for Professor Tesema's class at NVCC.
The pressure of a sample of gas is measured with an open-end manometer, partially shown to the right. The liquid in the manometer is mercury. Assuming atmospheric pressure is 29.92 in. Hg, determine the pressure of the gas in:
For an open-end manometer that has the liquid level lower on the open-ended side, we use the equation below:
Pgas = pressure of the gas
Patm = atmospheric pressure
h= difference in liquid level height
p = density
g = acceleration due to gravity
