Where the above slope is given,  the discharge of the farmer's channel is 1.606 m^3/s.

The discharge (Q) of a channel is given by the equation:

Q = A * v

where A is the cross-sectional area of the channel and v is the velocity of the water.

The cross-sectional area of the channel (A) is given by:

A = depth * width

A = 1 m * 3.8 m

A = 3.8 m^2

To find the velocity (v), we can use the Manning's equation:

v = (1/n) * (R^(2/3)) * (S^(1/2))

where R is the hydraulic radius of the channel, given by:

R = A / P

where P is the wetted perimeter of the channel, given by:

P = 2 * depth + width

Substituting the values given, we get:

P = 2 * 1 m + 3.8 m

P = 5.8 m

R = A / P

R = 3.8 m^2 / 5.8 m

R = 0.655 m

Now we can find the velocity (v):

v = (1/0.03) * (0.655^(2/3)) * (0.0004^(1/2))

v = 0.422 m/s

Finally, we can find the discharge (Q):

Q = A * v

Q = 3.8 m^2 * 0.422 m/s

Q = 1.606 m^3/s

Therefore, the discharge of the farmer's channel is 1.606 m^3/s.

a. Convert from litres to m³.

120000mL=120000cm³

120000cm³/100³=0.12 m³.

b. Rate of discharge.

If  0.12 m³ where discharged in 25 seconds, the rate of discharge is:

0.12m³/25s = 0.0048m³/s.

Let's refer to the fluid mechanics equation that relates volume flow, area and velocity. This is the formula:

\(\frac{dV}{dt}=Av\); where the expression \(\frac{dV}{dt}\) is the volume flow rate (in m³/s); A is the cross-sectional area of the pipe (in m²), and v is the velocity flow (in m/s).

a. Solve the equation for v.

\(\frac{dV}{dt}=Av\\ \\(\frac{dV}{dt})/A=v\\ \\v=(\frac{dV}{dt})/A\)

b. Calculate the cross-sectional area of the pipe.

The cross-sectional area of the pipe is a circle. Hence, the formula of this area is:

\(A=\pi r^{2}\)

We'll have to convert the diameter to meters, because the formula for flow velocity needs the area in m². Let's go ahead and do that.

\(50mm/1000=0.05m\).

We were given the diameter, and the formula uses the radius, but the radius is just half of the diameter, therefore, we can substitute in toe formula like this:

\(A=\pi (\frac{0.05}{2} )^{2}=0.0020m^{2}\)

c. Substitute in the new expression for velocity flow and calculate.

\(v=(\frac{dV}{dt})/A\\ \\v=(\frac{0.048m^{3} }{1s})/(0.0020m^{2} )\\\\ v= 24m/s\)

Answer:

The power needed to drive this pump assuming  and efficiency of 75% is 1874.0 watts (W)

Explanation:

Solution:

Given that:

Velocity  = 2 m/s

Pressure = 100 kPa

The pump exit is =4 m

Efficiency 75%

Thus,

We apply the method called the Bernoulli's equation between two reservoirs

p₁ / ps + v₁²/2g + z₁

=p₂/ps/v₂²/2g +z₂ + hL

The density of gasoline (pg) is = 680 kg m³

The gravity of acceleration is known to be  =9.81 m/s²

So,

100/680 *9.81 + 2²/2 *9.81 + 1 = 500/ 680 * 9.81 + 3²/2 * 9.81 +4 + hL

16. 2 = 79.41 + hL

hl =79.41 - 16.2

hL =63.21 m

the unit weight of gasoline is(γ) = 680 * 9.81 = 6670.8 m/s

Now we find the efficiency

The efficiency  (η) = The output power /Input power

Where hL =H

The input power = γ * Q * H/0.75

=6670.8 *12/3600 * 63.21

=6670.8 * 0.333 * 63.21

=6670.8 *0.2107

The engineers should use dimensions of approximately 8.93 ft by 8.93 ft by 6.67 ft to create an acceptable aquarium with the least amount of glass.

To minimize the amount of glass used in the aquarium, the engineers should choose dimensions that minimize the surface area of the aquarium while still holding 500 ft^3 of water.

Since the aquarium has a square bottom, let x be the length of one side of the bottom, and let h be the height of the aquarium. Then the volume of the aquarium is given by:

V = x^2 h

We want to find the values of x and h that satisfy the constraint V = 500 ft^3 and minimize the surface area of the aquarium. The surface area of the aquarium is given by:

A = x^2 + 4xh

To minimize A subject to the constraint V = 500 ft^3, we can use the method of Lagrange multipliers. The Lagrangian function is:

L(x,h,λ) = x^2 + 4xh + λ(500 - x^2 h)

Setting the partial derivatives of L with respect to x, h, and λ equal to zero, we get:

2x + 4h - λx^2 = 0

4x - λx^2 = 0

500 - x^2 h = 0

From the second equation, we get:

λ = 4/x

Substituting this into the first equation, we get:

2x + 4h - (4/x)x^2 = 0

Simplifying, we get:

x^3 + 2hx - 1000 = 0

We can solve this equation for x numerically using a calculator or computer program. The positive solution is:

x ≈ 8.93 ft

Substituting this back into the third equation, we get:

h ≈ 6.67 ft

Therefore, the engineers should use dimensions of approximately 8.93 ft by 8.93 ft by 6.67 ft to create an acceptable aquarium with the least amount of glass.

Answer:

true

Explanation:

The minimum pressure at which the water-supplying pump must operate is approximately 2.45 x 10⁶ Pa or 2450 bar.

To calculate the minimum pressure at which the water-supplying pump must operate, we need to use the formula for the volumetric flow rate of a fluid:

Q = A * v

where,

Q =the flow rate

A = the cross-sectional area of the hole

v = the velocity of the fluid.

We can use this formula to determine the velocity of the water, and then use the Bernoulli equation to determine the minimum pressure.

From the question:

ṁ=0.05 kg/s

ρ= 996 kg/m

d= 0.02 cm

Calculating the area of the hole:

A = (π/4) * (d²)

where,

d is the diameter of the hole, and pi is approximately 3.14.

d = 0.02 cm = 0.0002 m

A = (3.14/4) * (0.0002 m)² = 1.57 x 10⁻⁷ m²

Using the mass flow rate to calculate the velocity of water:

Q = ṁ / ρ

where,

Q = the volumetric flow rate

ṁ = the mass flow rate

ρ = the density of water.

Q = (0.05 kg/s) / (996 kg/m³)

Q = 5 x 10⁻⁵ m³/s

Using the area of the hole to find the velocity of water

v = Q / A

v = (5 x 10⁻⁵ m³/s) / (1.57 x 10⁻⁷m²)

v = 318.8 m/s

Using the Bernoulli equation to find the pressure:

P = Patm + (1/2) * ρ * v²

where,

P = the pressure

Patm = the atmospheric pressure

ρ =the density of water

v = the velocity of the water.

P = Patm + (1/2) * (996 kg/m³) * (318.8 m/s)²

Hence, the minimum pressure at which the water-supplying pump must operate is approximately 2.45 x 10⁶ Pa or 2450 bar.
