Answer:
The temperature of the strip as it exits the furnace is 819.15 °C
Explanation:
The characteristic length of the strip is given by;
The Biot number is given as;
< 0.1, thus apply lumped system approximation to determine the constant time for the process;
The time for the heating process is given as;
Apply the lumped system approximation relation to determine the temperature of the strip as it exits the furnace;
Therefore, the temperature of the strip as it exits the furnace is 819.15 °C
Answer:
Explanation:
The capacitive reactance of the capacitor is determined by
When
and
(The capacitive reactance will be reduced into 1/2 times of the previous capacitive reactance)
Answer: The solution can be found in the attached
Explanation:
Answer:
Explanation:
Given that :
Nominal size (d) = 34 mm ,
specification : Medium drive fit .
Outside diameter (d) =45 mm
Length (l) = 50 mm
Material Specification : AISI 1020 CD steel
Tensile strength = 700 MPa
Yield strength = 600 MPa
Yield strength of steel =390 MPa
See attachment for the explanation
Answer:
The claim is false and violate the zeroth law of thermodynamics.
Explanation:
Zeroth law of thermodynamics refers to thermal equilibrium among elements. It states that elements which different temperatures will reach the same temperature at the endgame if they are close enough to interact each other. This temperaure is called <em>equilibrium temperature and it is always a intermediate value between the element with highest temperature and the element with the lowest one. So there is no way </em> a cup of cold coffee on a table can warm up to 80°C picking up energy from the surrounding air at 25°C because the cup can only reach a temperature closer to the surrounding air temperature which will be the equilimbrium temperature for that case.
