Whoops...sorry I meant to put in what each letter stood for.
Q = cm\DeltaT
\DeltaT - change in temp
m - mass
c - specific heat (which is given)
1 ton = 2000 lbs = 907.184 kg
kW = Btu / 3414
Q = (.8 BTU/lb/F)(907.184kg)(20C)
Q =
Can I convert the BTUs to kW just by using the...
[SOLVED] Heat problem
Homework Statement
The manager of a fried chicken place wishes to store a ton of poultry at 0 degrees Fahrenheit. Initially the poultry is at 20 degrees Celsius. Calculate the energy in BTUs that is removed in this cooling for storage process.
Assume that the poultry...
So would the relative humidity at 68F/20C be 8.65g/m^3, being that it's 50%?
And the relative humidity at 98.6F/37C would be 44g/m^3 since it is 100%?
Does the question want to how much MORE water the membranes would have to produce to completely saturate the air at 37 degrees C?
Homework Statement
If a person breathes 10 liters per minute of air at 68 degrees F and 50% relative humidity, how much water per day must the internal membranes supply to saturate the air at 98.6 degrees F? (Assume all the moisture is exhaled). I f each gram of water extracts 580 calories as...
