Answer:
Q=1847kJ
Explanation:
Through laboratory tests, thermodynamic tables were developed, these allow to know all the thermodynamic properties of a substance (entropy, enthalpy, pressure, specific volume, internal energy etc ..)
through prior knowledge of two other properties such as pressure and temperature.
The heat that is being applied to water is given by the following equation using the first law of thermodynamics.
Q=m(h2-h1)
then to solve this problem we must find the enthalpy of state 1 and 2.
for state 1.
t=80C
x=0.6
h1=1720kJ/Kg
for state 2.
t=80C
X=1(saturated vapor)
h2=2643kJ/Kg
solving
Q=m(h2-h1)
Q=2(2643-1720)
Q=1847kJ
ANSWER: Although more than 25 types of elements can be found in biomolecules, six elements are most common. These are called the CHNOPS elements; the letters stand for the chemical abbreviations of carbon, hydrogen, nitrogen, oxygen, phosphorus, and sulfur. HOPE THIS HELPS!

Explanation:
Answer:
0.740833917 ton/hr
Explanation:
Given:
Cooling load, 8890.007 Btu/hr = 2.605 kW
Room size = 180
According to the thumb rule
1 ton of refrigerant = 12000Btu
Hence for 8890.007 Btu/hr,
the mass flow rate of the refrigerant is =8890.007 / 12000
= 0.740833917 ton per hr
Hence, mass flow rate is 0.740833917 ton/hr
