initially at 278 K. If steam

ow rate is 4 gm/min, estimate how long it takes to heat

the water to 322 K. Assume the process is at constant pressure (at 100 kPa) and kinetic

energy of the incoming steam is negligible. Further assume that there is no evaporation

to the surrounding. If needed make other necessary assumptions and clearly identify

them.

My attempt- I know i need to look up values in a table for the internal energy of steam etc, I think i need to use dU=dQ-dW and possibly another equation.
