Question

If the gauge pressure of a gas is 114 kPa, what is the absolute pressure?

A. 220 kPa
B. 14 kPa
C. 50 kPa
D. 214 kPa​

Answer 1

your answer is 214kPa

Step-by-step explanation:

Answer 2

D. 214 kPa

Step-by-step explanation:

The absolute pressure is given by:

`p = p_a + p_g`

where

p is the absolute pressure

`p_a \sim 100 kPa` is the atmospheric pressure

`p_g` is the gauge pressure

In this problem, we have

`p_g = 114 kPa`

So, the atmospheric pressure is

`p = 100 kPa + 114 kPa = 214 kPa`
