Answer:
18.62 m/s
Explanation:
Given that:
A liquid with a density of 900 kg/m 3 is stored in a pressurized, closed storage tank.
Diameter of the tank = 10 m
The absolute pressure in the tank above the liquid is 200 kPa = 200, 000 Pa
At pressure of 200 kPa ; the final velocity = 0
Atmospheric pressure at 5cm = 101325 Pa
We are to calculate the initial velocity of a fluid jet when a 5cm diameter orifice is opened at point A?
By using Bernoulli's theorem between the shaded portion in the diagram;
we have:
where;
Pa = atmospheric pressure = 101325 Pa
= density of liquid = 900 kg/m³
= initial velocity = ???
g = 9.8 m/s²
= height of the hole from the buttom
= height of the liquid surface from the button
Thus, the initial velocity of the fluid jet = 18.62 m/s
Answer:
The description of the given scenario is described in the explanation segment below.
Explanation:
- As a charge passes through some kind of potential gap, the electrical task is undertaken as well as energy will be transferred.
- The Potential difference seems to be an amount of work performed per unit charge and is denoted by "V" as well as a charge is denoted by "Q".
<u>The energy transferred could be determined by using the following equation or formula:</u>
⇒ Energy transferred = charge × potential difference
B. At the equator
Explanation:
The energy coming from the Sun hits the Earth's surface at different angles, depending on the latitude of the place. The more perpendicular the ray of lights hit the surface, the more the energy transmitted to the Earth's surface, the warmer the location.
The angle at which the ray of lights hit the Earth is related to the latitude: in particular, the ray of lights arrive perpendicular at the equator (
), they arrive at larger angle in the United States (which is located at intermediate latitudes) and they arrive at the largest angles at the poles. For this reason, the sun's most energy is concentrated at the equator.
Answer:
17640
Explanation:
Power = workdone/time
Power = (force x displacement)/time
Power = (mg x 60)/60
Power = (1800 x 9.8 x 60)/60
=> power = 17640 watt
15 you get 3 Multiply it by 5 and get 15
