## Homework Statement

How do we obtain:

w = q - Δh

## Homework Equations

## The Attempt at a Solution

If you neglect the second half of the SFEE and simplify we get:

What is the next step from the last line in the above image to

w = q - Δh

I mean dw/dt = dq/dt - Δh

so if we multiply by dt we get:

dw = dq - Δh(dt)

w = q -

Then I assume this should be integrated? If yes, how? Can't seem to get my head round it.

Also, what is the difference between w = q - Δh and w = q - Δu? I know u is specific internal energy and h is specific enthalpy but the above seems to suggest they're the same?
