I’m sorry , but reading this is confusing ...
can you explain please ?
^-^
Answer:
<em>0.0386 hr</em>
<em></em>
Explanation:
Area = 565 cm^2 = 0.0565 m^2 (1 cm^2 = 0.0001 m^2)
flux state rate = 220 mole/m^2-day
<em>There are 24 hrs in a day,</em> therefore rate in hrs will be
220/24 = 9.17 mole/m^2-hr
mass of water = 0.4 kg
molar mass of water = (1 x 2) + 16 = 18 kg/mole
therefore,
<em>mole of water = mass of water/molar mass of water</em>
mole of water = 0.4/18 = 0.02 mole
<em>mole flux = mole/area</em> = 0.02/0.0565 = 0.354 mol/m^2
<em>time that will be taken will be for water to pass = mole flux/mole flux rate</em>
time = 0.354/9.17 = <em>0.0386 hr</em>

Midnight on the birthday. Hope this helps!
The net resultant direct force and angle on the vane is created when the water jet exits the vane at position 2 with 92% of its initial velocity.
<h3>What is mean by velocity?</h3>
- The speed at which a body or object is moving determines its direction of motion. A scalar quantity, speed is primarily. As a matter of fact, velocity is a vector quantity.
- The rate at which distance changes is what it is. It measures the displacement's rate of change. A body's velocity is defined as its speed in a particular direction.
- Velocity is a measure of how quickly a distance changes in relation to time. Having both magnitude and direction, velocity is a vector quantity.
- The rate of change in a body's displacement with respect to time is referred to as velocity. In the SI, m/s is its unit.
Given,
External angle of Curved Vane = 158°
mean velocity at 1 = 12 m/s
Volumetric flow rate =
mean velocity at
i) Force exerted in x - friction A C 1 = Volume
i
The complete question is:
A horizontal jet of water strikes a curved vane as shown in Figure C.1. The external angle of the curved vane is 158°.The mean velocity and volumetric flow rate of the water jet at position 1 are 12 m/s and 55 m³/h respectively. Due to friction, the water jet leaves the vane at position 2 with 92 % its original velocity.
(i) Direct force exerted by the water jet on the vane in the x - direction.
(ii) Direct force exerted by the water jet on the vane in the y - direction.
(ii) Net resultant direct force and angle on the vane.

Answer:
Tesla CEO Elon Musk tweeted that the company's stock was too high, and it immediately dropped in value. The tweet may have violated a deal Musk made with the SEC about his tweets and Tesla. Musk also tweeted patriotic lyrics, said his girlfriend Grimes is mad at him, and noted that their child is due on Monday
