Question

Gauge pressure is the pressure measured

a. with respect to the atmospheric pressure 1,000 km above sea level

b. with respect to the atmospheric pressure

c. 1.00 m below the water surface

d. with respect to vacuum

To obtain gauge pressure from absolute pressure,

a. one makes it equal to zero

b. one subtracts the atmospheric pressure from the absolute pressure

c. one equates it to the absolute pressure

d. one adds it to the atmospheric pressure to the absolute pressure

Which of the following is not a correct atmospheric pressure?

a. 10,100 Pa

b. 14.7 psi (pound per square inch)

c. 10,300 kg-force/m^2

d. 1 atm

Remember

Absolute pressure = Atmospheric pressure + Gauge Pressure

Q1.

Gauge pressure is measured w.r.t to Vaccum

Correct option is D

From above equation

G.P = A.P - Patm

Correct option is B.

Q3.

Patm = 1 atm = 1.013*10^5 Pa = 1.013*10^5 N/m^2 = 14.7 psi

So Option A and C are not correct. (If multiplal choices are correct)

other check the value given in Pa, it should be 101000 Pa, then correct option will be C
