    1. The problem statement, all variables and given/known data
    Helium is stored in a tank initially at temperature To and pressure Po. It starts coming out through an opening (pipe outlet) at a constant mass flow rate of mdot. Calculate the decrease in temperature and pressure of the tank (assuming no heat loss to the surroundings) as a function of time.

    2. Relevant equations


    3. The attempt at a solution

    Hello ishan1992. Welcome to the forum.

    To get help with your homework you need to show that you have made some attempt to solve the problem yourself. We are not supposed to just do your homework for you. If you can show that you made an attempt, or ask for help on a particular place that you are stuck, then we will be glad to help. But we can't just answer your homework questions for you.

    I will give you one hint here. Do you know the ideal gas law?
