Answer:
<em>0.0386 hr</em>
<em></em>
Explanation:
Area = 565 cm^2 = 0.0565 m^2 (1 cm^2 = 0.0001 m^2)
flux state rate = 220 mole/m^2-day
<em>There are 24 hrs in a day,</em> therefore rate in hrs will be
220/24 = 9.17 mole/m^2-hr
mass of water = 0.4 kg
molar mass of water = (1 x 2) + 16 = 18 kg/mole
therefore,
<em>mole of water = mass of water/molar mass of water</em>
mole of water = 0.4/18 = 0.02 mole
<em>mole flux = mole/area</em> = 0.02/0.0565 = 0.354 mol/m^2
<em>time that will be taken will be for water to pass = mole flux/mole flux rate</em>
time = 0.354/9.17 = <em>0.0386 hr</em>
Answer:
For fluid power, a working fluid is a gas or liquid that primarily transfers force, motion, or mechanical energy. ... Examples without phase change include air or hydrogen in hot air engines such as the Stirling engine, air or gases in gas-cycle heat pumps, etc.
Explanation:
Answer:
A machine consumes energy whereas an engine produces energy. Engine converts heat energy to Mechanical Energy but machine converts all forms of energy to mechanical energy except heat energy. A engine runs a machine,without a engine a machine can't run.
Explanation:
Answer:
class helloSarah {
public static void main(String [] args) {
Name = "Hello Sarah";
System.out.print(Name);
}
}
Explanation:
<em>The question seem incomplete; However, since the program is incorrect, I'll assume the question is to correct the given code;</em>
The program segment was written in Java and the correct program is in the answer section
<u>See bold texts for line by line explanation </u>
This line declares the class name
<em>class helloSarah {</em>
This line declares the main method of the program
<em>public static void main(String [] args) {</em>
This line initializes string variable Name
<em>String Name = "Hello Sarah";</em>
This line prints the initialized variable
<em>System.out.print(Name);</em>
<em>}</em>
<em>}</em>

A molecule of natural gas is made up of carbon and hydrogen. When the hydrogen is segregated from the carbon and filled into a fuel cell, it fuses with oxygen to produce water, electricity, and heat. The carbon is released as carbon dioxide in smaller quantities than from gas turbines
