The results illustrated here were hidden by means of Obscurational Cloaking technology.

This technology is used to hide, conceal, obscure, and withhold results.

A fluid in an aquifer is 23.6 m above a reference datum, the fluid pressure (in gage pressure) is 4390 n/m2 and the flow velocit

Phoenix [80]

As per Bernuolli's Theorem total energy per unit mass is given as

$\frac{P}{\rho} + \frac{1}{2}v^2 + gH = E$

now from above equation

$P = 4390 N/m^2$

$\rho = 0.999 * 10^3$

$v = 7.22 * 10^{-4} m/s$

$H = 23.6 m$

now by above equation

$\frac{4390}{0.999*10^3} + \frac{1}{2}*(7.22*10^{-4})^2 + 9.8*23.6 = E$

$E = 235.7 J/kg$

Part B)

Now energy per unit weight

$U = \frac{E}{g}$

$U = \frac{235.7}{9.8}$

$U = 24 m$

Diesel fuel is used in the engine of trucks that carry dirt fruit and other cargo. Fuel is burned in engines to make the motor m

Marina86 [1]

Answer: Fuel is burned in engines to make the motor move.

( Chemical to Mechanical )

Explanation:

during combustion of the diesel ( when the fuel is burnt in the engine of the vehicle, the diesel ( chemical energy ) is transformed or converted to Mechanical energy. This mechanical energy is what the truck uses in moving. Without the combustion of the fuel the vehicle won’t move and the combustion of diesel is achieved through compression unlike that of fuel.

Use newton's first law of motion to explain why you feel tossed around whenever a roller coaster goes over a hill or through a l

ikadub [295]

Newton's first law states that an object at rest will stay at rest && an object in motion will remain in motion unless acted on by another force. With that being said you feel tossed around because you are initially at rest but when you ride the roller coaster you take it's course of motion.

Hoped this helped!

Water is falling on a surface, wetting a circular area that is expanding at a rate of 4 mm2 /s. How fast is the radius of the we

STALIN [3.7K]

Answer:

The radius of the wetter area expands at a rate of $4.244\times 10^{-3}$ milimeters per second when radius is 150 milimeters.

Explanation:

From Geometry we remember that area of a circle is described by this expression:

$A =\pi\cdot r^{2}$ (Eq. 1)

Where:

$r$ - Radius of the circle, measured in milimeters.

$A$ - Area of the circle, measured in square milimeters.

Then, the rate of change of the area in time is derived by concept of rate of change, that is:

$\frac{dA}{dt} = 2\pi\cdot r\cdot \frac{dr}{dt}$ (Eq. 2)

Where:

$\frac{dr}{dt}$ - Rate of change of radius in time, measured in milimeters per second.

$\frac{dA}{dt}$ - Rate of change of area in time, measured in square milimeters per second.

Now the rate of change of radius in time is cleared within equation above:

$\frac{dr}{dt} = \left(\frac{1}{2\pi\cdot r}\right)\cdot \frac{dA}{dt}$

If we know that $r = 150\,mm$ and $\frac{dA}{dt} = 4\,\frac{mm^{2}}{s}$ , then the rate of change of radius in time is:

$\frac{dr}{dt} = \left[\frac{1}{2\pi\cdot (150\,m)} \right] \cdot \left(4\,\frac{mm^{2}}{s} \right)$

$\frac{dr}{dt}\approx 4.244\times 10^{-3}\,\frac{mm}{s}$

The radius of the wetter area expands at a rate of $4.244\times 10^{-3}$ milimeters per second when radius is 150 milimeters.
