Question

DERIVE THE EXPRESSION SI unit
FOR PRESSURE

Answer 1

Answer:

Pressure—the effect of a force applied to a surface—is a derived unit, obtained from combining base units. The unit of pressure in the SI system is the pascal (Pa), defined as a force of one Newton per square meter. The conversion between atm, Pa, and torr is as follows: 1 atm = 101325 Pa = 760 torr.

Answer 2

Answer:

Explanation:

pressure= Force /acceleration

unit of pressure= unit of force/unit of acceleration

                           =Newton/m/sec2 or pascal
