Calculate Mass Flow rate of cooling water through condenser?

Click For Summary
SUMMARY

The discussion centers on calculating the mass flow rate (m(dot)) of cooling water through a condenser with a known mass flow rate of 60 kg/s for steam. The initial conditions include a pressure of 50 kPa and a quality of 95%, while the final state is a saturated liquid at the same pressure. The cooling water experiences a temperature change of 15 degrees Celsius. The open system version of the first law of thermodynamics is applicable for determining the energy balance in this scenario.

PREREQUISITES
  • Understanding of thermodynamics, specifically the first law for open systems.
  • Knowledge of steam properties at various pressures and qualities.
  • Familiarity with mass flow rate calculations in fluid dynamics.
  • Basic principles of heat transfer and temperature differentials.
NEXT STEPS
  • Study the first law of thermodynamics for open systems in detail.
  • Research steam tables to find properties at 50 kPa for accurate calculations.
  • Learn about heat exchanger design principles and calculations.
  • Explore methods for calculating mass flow rates in cooling systems.
USEFUL FOR

Engineers, thermodynamics students, and professionals involved in HVAC systems or any applications requiring heat exchange calculations will benefit from this discussion.

This is a homework problem that was posted in another forum, so there is no template
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)?

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?
