Example 1.
A bourdon gauge is attached to a boiler which is located at sea level with a reading pressure of 7 bar.
If atmospheric pressure is 1.013 bar, calculate the absolute pressure in that boiler (in kN.m2
).
𝑃𝐺 = 7 𝑏𝑎𝑟 = 7 𝑥 105
𝑁/𝑚2
𝑃𝑎𝑡𝑚 = 1.013 𝑏𝑎𝑟 = 1.013 𝑥 105
𝑁/𝑚2
𝑃𝑎𝑏𝑠 = 𝑃𝐺 + 𝑃𝑎𝑡𝑚 = (7𝑥 105) + (1.013 𝑥 105) = 8.013 𝑥 105
𝑁/𝑚2
𝑃𝑎𝑏𝑠 = 801.3 𝑘𝑁/𝑚2

3. Calculate the absolute pressure of air in the compressor cylinder if the pressure gauge is
2500N/m2
. (Assume atmospheric gauge is 101.3 kN/m2
)
4. A pressure gauge is attached to a reservoir containing water which shows value of 20kN/m2
.
Calculate:
i. The pressure head of water, h
ii. The absolute pressure in kN/m2
if the atmospheric pressure is 101.3kN/m2
.
