Answer:
, ,
Explanation:
Let assume that steam has a fully developed and turbulent flow and that tube is smooth and thin-walled. The steam is heated while flowing through the tube. The Nusselt number is given by the Dittus-Boelter equation:
Properties of steam at given pressure and temperature are:
The Reynolds and Prandtl numbers are, respectively:
(which demonstrates the reasonability of the supposition of turbulent flow)
The Nusselt number is:
The Nusselt number has the following definition:
The heat transfer coefficient is:
The convection is the dominant heat transfer mechanism, then:
Answer:
The potential energy increases if the orbital radius increases.
Explanation:
The orbital radius of the electron increases means the distance from the nucleus of the hydrogen atom increase.
The nucleus is positively charged .
The potential energy is given by P.E = -
where Z is the atomic number
r is the radius
The negative sign indicates that the electron which is revolving is bound to nucleus.
As the radius and potential energy are inversely proportional it is clear that when <em>radius increase</em> the<em> potential energy become less negative </em>which means the potential energy increases when the orbital radius increase.
The orbital period could be obtained from the question as 8.98 * 10^7 m.
<h3>What is the orbital period?</h3>
We know that the solar system is composed of the sun and the planets. The planets are known to move around the sun in concentric circles. Following the heliocentric model of the solar system, the sun is at the center of the solar system at all times and all the other planets tend to move round the sun at a good distance that is appropriate for each.
Now we have that;
T = √4π^2r^3/GM
T = period of the orbit
r = radius of the orbit
G = gravitational constant
M = mass of the planet
Hence, we have;
R = ∛T^2GM/4π^2
R =∛ (26 * 60 * 60)^2 * 6.67 * 10^-11 * 4.9 * 10^25/ 4 * (3.142)^2
R = ∛2.86 * 10^25/39.49
R = 8.98 * 10^7 m
