Roughly 13.8 billion years old according to science
PH of 4 is Acidic and its property is to turn blue litmus red
The heat and energy of coal burning is more easier and more efficient to turn into electricity than any method using renewable resources.
Answer:
You are asked to design a cylindrical steel rod 50.0 cm long, with a circular cross section, that will conduct 170.0 J/s from a furnace at 350.0 ∘C to a container of boiling water under 1 atmosphere.
Explanation:
Given Values:
L = 50 cm = 0.5 m
H = 170 j/s
To find the diameter of the rod, we have to find the area of the rod using the following formula.
Here Tc = 100.0° C
k = 50.2
H = k × A ×
Solving for A
A =
A =
A = = 6.77 × m²
Now Area of cylinder is :
A = d²
solving for d:
d =
d = 9.28 cm
