Calculate Mass Flow rate of cooling water through condenser?

Click For Summary

Discussion Overview

The discussion revolves around calculating the mass flow rate of cooling water through a condenser, given specific conditions related to the condenser and the cooling process. The context includes aspects of thermodynamics and fluid mechanics, particularly focusing on the application of the first law of thermodynamics in an open system.

Discussion Character

  • Homework-related, Technical explanation

Main Points Raised

  • One participant states the mass flow rate of the condenser is 60 kg/s and provides initial and final pressure and quality conditions.
  • Another participant questions whether the problem is a homework assignment.
  • A participant confirms that it is indeed a homework problem.
  • One participant assumes that the fluid being cooled is steam and inquires about the relevant application of the first law of thermodynamics for the cooling process.

Areas of Agreement / Disagreement

There is no consensus on the specifics of the calculation or the assumptions regarding the fluid being cooled, as participants are still exploring the problem and raising questions.

Contextual Notes

Participants have not yet established the assumptions regarding the properties of the cooling water or the steam, nor have they detailed the mathematical steps needed to arrive at the mass flow rate.

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)?

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?
