The amount of fluid that moves past a point in area A per unit of time is known as the flow rate.
<h3>How do you find average velocity from flow rate?</h3>
- The amount of fluid that moves past a point in area A per unit of time is known as the flow rate. Here, a uniform pipe carrying the shaded fluid cylinder passes point P in time t. The cylinder's capacity is Ad, its average velocity is v=d/t, and its flow rate is Q=Ad/t=Av.
- The average fluid velocity for laminar flow through a pipe is equal to half of the fluid's greatest velocity at the pipe's center. The Hagen-Poiseuille equation is shown above. Since there is no acceleration in a steady and uniform flow, there is no force acting in the direction of the flow.

Answer:
Acceleration is the rate of change of velocity. Usually, acceleration means the speed is changing, but not always. When an object moves in a circular path at a constant speed, it is still accelerating, because the direction of its velocity is changing.

The reaction is:
From the equation, he limiting reactant is the oxygen.
Assuming 100% yield, all of the oxygen must react to form water.
1000 mol * (1 mol ÷ ½ mol ) = 2000 moles water

Answer:
5.6875 × 10^(10) electrons
Explanation:
To some this we will use the formula;
q = ne
Where;
q is charge
n is number of electrons
e is electron charge = 1.6 × 10^(-19) C
We are given q = -9.10 nc
1 nc = 10^(-9) C
Thus;
q = -9.1 × 10^(-9) C
Since q is negative, then e = -1.6 × 10^(-19) C
Thus;
-9.1 × 10^(-9) = n(-1.6 × 10^(-19))
n = -(9.1 × 10^(-9))/(-1.6 × 10^(-19))
n = 56875000000 electrons = 5.6875 × 10^(10) electrons
