Question

If mercury height in a glass tube is 50cm, find the pressure.

Answer 1

Answer

We can do it 2 ways

Using classical formula

Pressure = hdg if you know density(d) of mercury

Or

We know 1atm pressure = 76cm of height of

mercury column

Xatm pressure =50 cm

X = 50/ 76 atmospheric pressure

X=0.657

Explanation:

Answer 2

Answer:

0.657

Explanation:

1atm=76cm height of mercury column

x atm=50 pressure

x=50/76 atmospheric pressure

x=0.657
