Question

write three different units of pressure and give relation between them​

Answer 1

Step-by-step explanation:

1 pascal = 10 dyne/cm 2 = 0.01 mbar. 1 atm = 101,325 Pascals = 760 mm Hg = 760 torr = 14.7 psi. The prefix "kilo" means "1,000", so one kilopascal = 1,000 Pa. Therefore, 101.325 kPa = 1 atm = 760 torr and 100 kPa = 1 bar = 750 torr. The prefix "mega" means "1,000,000", so one megapascal = 1,000 kPa = 1,000,000 Pa.

Answer 2

Pressure is the effect of a force applied to an area of any surface. The basic unit of pressure is obtained from combining base units which are force over area.

Pressure=Force/Area

Unit of force is: Newton(N)

Unit of Area is: m²(metre)

So the basic unit of pressure is: P=N/m²

And the unit of pressure in SI system is Pascal which is denoted by ‘Pa’.

1 Pa = 1 N/m²
