I wouldn’t smell like anything carbon monoxide is an odorless gas
Answer:
227.5Secs
Explanation:
How long it will take To get to temperature 320 degrees and it's thermal time is 227.5 Seconds and 47.8 respectively. Kindly check attached file for how this is gotten.
To develop the problem it is necessary to apply the concepts related to the ideal gas law, mass flow rate and total enthalpy.
The gas ideal law is given as,
Where,
P = Pressure
V = Volume
m = mass
R = Gas Constant
T = Temperature
Our data are given by
Note that the pressure to 38°C is 0.06626 bar
PART A) Using the ideal gas equation to calculate the mass flow,
Therfore the mass flow rate at which water condenses, then
Re-arrange to find
PART B) Enthalpy is given by definition as,
Where,
= Enthalpy of dry air
= Enthalpy of water vapor
Replacing with our values we have that
In the conversion system 1 ton is equal to 210kJ / min
The cooling requeriment in tons of cooling is 437.2.
Answer:
Explanation:
For an isolated system (one that does not exchange matter of energy with its surroundings) entropy tends to raise.
The entire universe might be considered as an isolated system, and thus the entropy of the universe tends to rise and it never lowers.
Note that this is for isolated systems, not any systems.
A certain system might have its entropy go down, but for that it must exchange energy with its surroundings, and the entropy of the surroundings will raise. The change of entropy of the surroundings plus the change of entropy of the system (remember their signs) will always be positive.
