A tank initially contained 500 kg of nitrogen. The tank has 4 valves connected to it. 20 kg of nitrogen entered the tank though valve 1, 70
kg of nitrogen left the tank through valve 2, 125 kg of nitrogen entered the tank through valve 3, and 200 kg of nitrogen left the tank
through valve 4. The final mass of nitrogen in the tank in kg is

Expert Solution

Step 1

$Given : Initial mass of nitrogen in the tank, m_{i} = 500 kg Mass entered the tank through valve 1, m_{1} = 20 kg Mass left the tank through valve 2, m_{2} = 70 kg Mass entered the tank through valve 3, m_{3} = 125 kg Mass left the tank through valve 4, m_{4} = 200 kg Find : The final mass of nitrogen in the tank in kg$
