The pressure gauges G_{1 and G_{2 installed on the system show pressure of ρ_G₁ = 5.00 bar and ρ_G₂ = 1.00 bar. The value of unknown pressure P is [Atmospheric pressure = 1.01 bar]}}

1. 1.01 bar
2. 2.01 bar
3. 5.00 bar
4. 7.01 bar

Correct Option: D

P = P_G₁ + P_G₂ + P_atm
P = 5 + 1 + 1.01 = 7.01 bar
