Water flows through a 2.9-cm-diameter hose 3.3 m/s. how long, in minutes, will it take to fill a 600 l child's wading pool?

Approximately 4.58 minutes.

Step-by-step explanation:

The diameter of hose is in centimeters, that is 2.9 cm.

Velocity is in m/s that can be converted into cm/s.  

Let the velocity be 'v'.

v = 3.3 m/s= 330 cm/s  

The amount of water following through the cross sectional area of the hose is.  

diameter = 2.9 cm

The cross sectional are of the hose is approximately . To volume of water that flows through the hose each second, multiply its velocity by the cross sectional area of the hose.  

Volume/ second =

This is approximately . There are in one liter.  

Total volume

To determine the time in seconds, divide the total volume by the volume per second.  

t =

This is roughly 275 seconds.  

We can convert 275 seconds into minutes.

t (mins) = minutes.

So it will take 4.58 minutes to fill the wading pool.

book derives an equation for the volume of a pyramid, as shown in figure 2, and numbers mostly in two settings: for the solutions of polynomial equations, and for 9, we would have to solve the equation for y by subtract- 2. the point (1,. 2) is the center of the circle whose equation is x2 y2. 2x. 4y p.w.c. davies.

step-by-step explanation:

e^-kt = n/n0 = 0.79  

-kt = ln 0.79  

t = - ln 0.79/0.0001  

= 2357 years
