friction drag = 54546 lbf

A coal barge is 1000-ft-long, 100-ft-wide, and is submerged in 12 feet of 60°F water. If it is being towed at 12 mph, the friction drag would be 54546 lbf.

What is a Friction drag?

Friction is the resistance that occurs when two objects rub together, such as air against an airplane. Friction contributes to drag.

Because the barge is rectangular, the flow over the submerged sides and bottom is assumed to behave like B.L. over a flat plate.

Effects at the corners and leading/trailing edges are not taken into account, which could lead to deviations from the analysis. Given the size of the barge, we expect these effects to be minor.

The term "complex power" refers to the mathematical representation of electrical power. It has both real and fictitious parts, just like a complex number.

The active power is represented by the real part, while the reactive power is represented by the imaginary part. The letter S is frequently used to represent it.

The complex conjugate of the rms current phasor and the rms voltage phasor make up the complex power (in VA). As a complex quantity, its real and imaginary parts are real power P and reactive power Q, respectively.

Since the magnitude of the complex power is the apparent power, we could write it as:

S=S∠θ v−θ i

​However, mathrm pf = cos(theta_v-theta_i) pf = cos(v i)

v i = cos 1 pf = 45 In this case, the value of the ta_v-theta_i v i is positive due to the exercise's knowledge that current lags voltage. The value of the complex power is:

The component in the solar cell that provides electrons to replace the electrons released by the dye is "a layer of graphite"

A layer of graphite will operate as a counter electrode at the glass/electrolyte border, delivering electrons to the solution to replace these electrons that go on to the FTO glass.

They are reintroduced into the cell on a metal electrode on the rear, commonly known as the counter electrode, after passing through the external circuit and flowing into the electrolyte. The electrons are subsequently returned to the dye molecules by the electrolyte, which regenerates the oxidized dye.

PV cells make use of a variety of semiconductor materials. When exposed to light, the semiconductor absorbs the energy and converts it to negatively charged particles in the material known as electrons. This increased energy permits electrons to flow as an electrical current through the material.

The drag of the disk is 3.38 X 10^4.

What is drag?

Drag is a force that opposes any object's relative motion with respect to a surrounding fluid in fluid dynamics. This might be present between two liquid layers or between a liquid and a solid surface.

The resistance to motion of a body through a fluid, such as water or air, is known as a drag force. The direction of the incoming flow velocity is opposed by a drag force. This is the relative speed of the fluid and the body.

Solution Explained:

Given,

Specific gravity(sg) = 0.87

Diameter = 0.01ft

Density of Oil (P) = [tex]sg_{ph20} = 0.87 X 1.94 = 1.6878 \frac{sl}{ft^3}[/tex]

Since the viscosity is 10000 times that of water, the Reynold number is

[tex]R_{E} = \frac{PvD}{meu} = \frac{1.6878 X 0.01 X 0.01}{0.234} = 7.21 X 10^-4[/tex]

Since RE < 1, the drag coefficient for normal flow is given as:
