Question

Convert 2 PSI to inches of H20.

Answer 1

well,

memorize this

standard pressure is
101.3kPa
760 torr
760 mmHg
14.5 PSI
1 atm

now, since all these are equal

2psi/14.5PSI=x mmHg/760mmHg

solve for x mmHg

then x mmWater= x mmHg* specificgravityHg

now, convert xmmWater to inches

x inch water= 25.4*xmmWhater
