1.1 Pressure in a Tank

Problem Statement:

A cylindrical tank contains air at a gauge pressure of 3 atm and an ambient atmospheric pressure of 1 atm. Calculate the absolute pressure inside the tank.

## Solution:

# Given values
P_gauge = 3 * 101325  # Gauge pressure in Pascals (1 atm = 101325 Pa)
P_atm = 1 * 101325  # Atmospheric pressure in Pascals

# Absolute pressure
P_abs = P_gauge + P_atm

# Output the result
print(f"Absolute pressure inside the tank: {round(P_abs/1e3,1)} kPa")

Absolute pressure inside the tank: 405.3 kPa
