Calculate Mass Flow rate of cooling water through condenser?

[Spencer1]

I have a condenser with a mass flow rate of 60kg/s,

an initial point 1: P=50kPa, Quality = 95% and

a final point 2: P = 50kPa that is saturated liquid.

cooling water flows through the condenser with a mass flow rate of m(dot) and has a delta temperature of 15 degrees Celsius.

how do i calculate m(dot)?

Is this a homework problem?

yes

I assume the fluid being cooled is steam? What is the open system version of the first law of thermodynamics applicable to the steam being cooled from beginning to exit of the condenser?
