Question

(a) Define SI unit of pressure
(b) The atmospheric pressure at a place is
650 mm of Hg. Calculate this pressure in
Pascals (Pa).
[88400 Pa]
Pressure in a water pipe on the ground floor of
a building is 100,000 Pa. Calculate the pressure
in water pipe on first floor at a height of 3 m.
[Density of water = 1000 kgm ?; g = 10 ms ?]
[70000 Pa]
P is the pressure at some point in a liquid. State
whether pressure P is a scalar or vector quantity.​

Answer 1

Explanation:

a. Pressure is the amount of force applied perpendicular to the surface of an object per unit area and the for it is p (or P). The SI unit for pressure is the pascal (Pa), equal to one newton per square metre (N/m2, or kg·m−1·s−2). Pascal is a so-called coherent derived unit in the SI with a special name and symbol.
