Problem 5
A gas tank is connected to a tube containing four different liquids: mercury (DRHg=13.534), beer
(DRbeer=1.015), water (T=20°C), and oil (DRoil=0.914), respectively. (DRgas=0.3)
a) Find PM in kPa.
b) Find PM if the temperature suddenly changes to 30°C.
c) If PM = 700 kPa and the heights are reduced to half of what they are in the problem, what
would be Pgas in kPa? Is this result possible?
Pgas = 400kPa
