SUMMARY

The discussion centers on calculating the amount of water needed to heat 1000 MW of energy from 18°C to 30°C using the specific heat of water, which is 4.184 J g–1 K–1. Participants clarify that MW (megawatts) represents power, while Joules represent energy, highlighting the need for correct unit conversions. The confusion arises from the relationship between power and energy in the context of heating water. To determine the required water mass, users must apply the formula involving specific heat and temperature change.

PREREQUISITES
  • Understanding of specific heat capacity
  • Knowledge of energy units (Joules and Watts)
  • Basic thermodynamics principles
  • Ability to perform unit conversions
NEXT STEPS
  • Learn how to apply the formula Q = mcΔT for heat transfer calculations
  • Research the relationship between power (Watts) and energy (Joules)
  • Explore the concept of specific heat in different materials
  • Investigate practical applications of heating calculations in engineering
USEFUL FOR

Students in physics or engineering, professionals in thermal management, and anyone involved in energy calculations or heating processes.

how much water would 1000 MW/J heat from 18 degrees to 30 degrees?

i am unsure of what formula [is there is one] to use...

so any help would be GREAT!

TIA:smile:

Hint: What's the specific heat of water? (What kind of units are MW/J? Did you mean Joules?)
 
i have the specfic heat of water... and the MW/J was my way of saying mega watts or joules.

the specific heat i have is 4.184 J g–1 K–1

what i can't figure out is how to get the amount of water. and i am not sure of what sort of answer i am going to get, or if the answers i am getting from playing around are correct.

i think i am confusing myself...:rolleyes:

What's the definition of specific heat? Look it up!

Those aren't the same thing, you know. :rolleyes: (Watts = power; Joules = energy.)
