1.01325 bar =
760 mm of mercury
29.92hg
2
Q
Gauge pressure:
Absolute pressure
A
Gauge pressure: Pressures above atmospheric pressure - does not depend on position always constant, can be negative .
Absolute pressure: the actual pressure at a given position .
3
Q
the increase in fluid pressure is due to?———-
A
to height
of the fluid only. It is independent of area and shape
4
Q
fluid pressure in the horizontal direction is ———?
A
constant if the
fluid is a continuous
5
Q
Pascal’s Law
A
Liquids transmit pressure equally in all directions
P1 = P2
f1/a1 = f2 / a2
