# Chemistry Flow rate?

How do i go about doing this...?

F1 flowing at a rate of 1.2 kg/min is mixed with a separate stream of F2. F2 enters the mixer at a rate of 2500 L/min at 105˚C and 1800 kPa(g). F1 consists only air and F2 consists only hydrogen.

Assuming ideal gas behaviour, derive the relationship between volume percent and

mole percent. Determine the mass flowrate (g/hr) of Stream P. Determine the volume composition in the Stream P.

this is a very straightforward problem.. follow these steps

.. (1) draw a box diagram and label the streams

.. . . . F1 = feed 1

.. . . .F2 = feed 2

.. .. . .P = product stream.. (there's only 1)

.. (2) write in what you know about these streams

.. (3) solve for the compositions in each stream

. .. . . .use mass balances

.. .. . ..use energy balances (if applicable)

... . .. .use ideal gas law (in this case)

.. (4) in some cases, you won't be able to solve for compositions

.. . . .directly and you'll have a series of equations in (3)

.. . . .you might need to use interations or linear algebra to solve

anyway.. this should get you started. The rest is simple. Can you finish?
