SI Units - Engineering

Q1:

The intensity of pressure at a certain place is 1 kg (f)/m2, the intensity of pressur e in SI units will be

A 47.88 N/m2

B 9.81 N/m2

C 4.882 N/m2

D 0.07013 N/m2

ANS:B - 9.81 N/m2

Intensity of pressure = 1kgf/m^2 then,

In S.I.UNITS
= 1kgf/m^2 x 9.80665 N.
= 9.81N/m^2.
