Answer:
a. Heat removal rate will increase
b. Heat removal rate will decrease
Explanation:
Given that
One end of rod is connected to the furnace and rod is long.So this rod can be treated as infinite long fin.
We know that heat transfer in fin given as follows

We know that area

Now when diameter will triples then :





So the new heat transfer will increase by 3 times.
Now when copper rod will replace by aluminium rod :
As we know that thermal conductivity(K) of Aluminium is low as compare to Copper .It means that heat transfer will decreases.
5.85 psig
Using a specific gravity of 0.75 as an average for red\automobile gasoline.
Water at standard conditions (60 degF) is 2.31 feet = 1 psig
80/2.31 then multiply x .75 to compensate for specific gravity of water being 1.0

Avoid leading and biased questions.
Answer:
Technician A says the use of a larger input piston gives the system a mechanical advantage or increase in the force available to do work. Technician B says the multiplication of force through a hydraulic system is directly proportional to the difference in the piston sizes throughout the system.
