Answer:
the minimum diameter of the bar is 1.634 in
Answer:
The maximum discharge rate of water is 4.6 L/s
Explanation:
Given data:
d=diameter=8 m
h=height=3 m
The mathematical expression for the theoritical velocity is:

The maximum discharge can be calculate by:

Here
Cd=coefficient of discharge=0.855

Answer:
b) Endothermic Chemical Reactions in a solid
Explanation:
Endothermic reactions consume energy, which will result in a cooler solid when the reaction finishes.
