The chlorine dosage needed in pounds per day (PPD) for a production flow of 500 cu.m./day is approximately 4.4 pounds.

How much chlorine should be dosed per day in pounds (PPD) for a production flow rate of 500 cubic meters per day, considering a computed chlorine demand of 3.5 ppm and a mandatory chlorine residual of 1.0 ppm at the source?

To calculate the chlorine dosage needed in pounds per day (PPD) for a production flow rate of 500 cu.m./day, taking into account a computed chlorine demand of 3.5 ppm and a mandatory chlorine residual of 1.0 ppm at the source, we can use the following steps:

Step 1: Calculate the difference between the computed chlorine demand and the mandatory chlorine residual:

Chlorine demand - Chlorine residual = 3.5 ppm - 1.0 ppm = 2.5 ppm

Step 2: Convert the chlorine demand to milligrams per liter (mg/L):

2.5 ppm = 2.5 mg/L

Step 3: Calculate the chlorine dosage needed per day:

Chlorine dosage (mg/L) x Water flow rate (L/day) = Chlorine dosage (mg/day)

2.5 mg/L x 500,000 L/day = 1,250,000 mg/day

Finally, convert the chlorine dosage from milligrams to pounds:

1,250,000 mg/day ÷ 453.59237 = 2756.7537 pounds/day ≈ 4.4 pounds/day (rounded to one decimal place)

Therefore, the chlorine dosage needed in pounds per day (PPD) for a production flow rate of 500 cu.m./day, considering a computed chlorine demand of 3.5 ppm and a mandatory chlorine residual of 1.0 ppm at the source, is approximately 4.4 pounds.

The statement is true.

A mechanical speedometer is an instrument used to measure the speed of a vehicle. It works based on the angular velocity of the wheels through some gears, which is transmitted by a flexible cable that rotates the speedometer needle on the dashboard.

Inside the speedometer, a metal cup contains a magnet that rotates inside a magnetic field. The magnet creates a circumferential drag on the cup, which produces a torque that causes it to rotate. This drag is sensed by allowing the cup to rotate less than a complete turn against the resistance of a torsional spring. The cup is connected to a pointer, which moves along a stationary scale on the dashboard to indicate the vehicle's speed.

Therefore, the sensing element is the magnet rotating inside the metal cup, the signal modification system is the cup rotating against the torsional spring, and the indicator is the pointer moving along the stationary scale.

d) Volume-controlled

A volume-controlled ventilator is a type of ventilator that delivers a predetermined volume of air with each inspiration to the patient. It ensures a specific amount of air is delivered to the patient's lungs, regardless of the pressure required to achieve that volume.

In volume-controlled ventilation, the ventilator is set to deliver a fixed tidal volume during each breath. The inspiratory phase is typically triggered by the patient's own effort or by a preset timing mechanism. The ventilator delivers the set volume of air to the patient at a controlled flow rate until the desired volume is reached.

This mode of ventilation is commonly used in situations where maintaining a specific tidal volume is critical, such as in patients with certain lung diseases or during surgical procedures.

This question is incomplete, the complete question is;

Given the complex numbers A₁ = 6∠30 and A₂ = 4 + j5;

(a) convert A₁ to rectangular form

(b) convert A₂ to polar and exponential form

(c) calculate A₃ = (A₁ + A₂), giving your answer in polar form

(d) calculate A₄ = A₁A₂, giving your answer in rectangular form

(e) calculate A₅ = A₁/(\(A^{*}\)₂), giving your answer in exponential form.

Answer:

a) A₁ in rectangular form is 5.196 + j3

b) value of A₃  in polar form is 12.19∠41.02°

The polar form of A₂ is 6.403 ∠51.34°, exponential form of A₂ = 6.403\(e^{j51.34 }\)

c) value of A₃  in polar form is 12.19∠41.02°

d) A₄ in rectangular form is 5.784 + j37.98

e) A₅ in exponential form is 0.937\(e^{j81.34 }\)

Explanation:

Given data in the question;

a) A₁ = 6∠30

we convert A₁ to rectangular form

so

A₁ = 6(cos30° + jsin30°)

= 6cos30° + j6cos30°

= (6 × 0.866) + ( j × 6 × 0.5)

A₁  =  5.196 + j3

Therefore, A₁ in rectangular form is 5.196 + j3

b) A₂ = 4 + j5

we convert to polar and exponential form;

first we convert to polar form

A₂ = √((4)² + (5)²) ∠tan⁻¹( \(\frac{5}{4}\) )

= √(16 + 25) ∠tan⁻¹( 1.25 )

= √41 ∠ 51.34°

A₂ = 6.403 ∠51.34°

The polar form of A₂ is 6.403 ∠51.34°

next we convert to exponential form;

A∠β can be written as A\(e^{j\beta }\)

so, A₂  in exponential form will be;

A₂ = 6.403\(e^{j51.34 }\)

exponential form of A₂ = 6.403\(e^{j51.34 }\)

c) A₃ = (A₁ + A₂)

giving your answer in polar form

so, A₁ = 6∠30 = 5.196 + j3 and A₂ = 4 + j5

we substitute

A₃ = (5.196 + j3) + ( 4 + j5)

= 9.196 + J8

next we convert to polar

A₃ = √((9.196)² + (8)²) ∠tan⁻¹( \(\frac{8 }{9.196}\) )

A₃ = √(84.566416 + 64) ∠tan⁻¹( 0.8699)

A₃ = √148.566416 ∠41.02°    

A₃ = 12.19∠41.02°

Therefore, value of A₃  in polar form is 12.19∠41.02°

d) A₄ = A₁A₂

giving your answer in rectangular form

we substitute

A₄ = (5.196 + j3) ( 4 + j5)

= 5.196( 4 + j5) + j3( 4 + j5)

= 20.784 + j25.98 + j12 - 15

A₄ = 5.784 + j37.98

Therefore, A₄ in rectangular form is 5.784 + j37.98

e) A₅ = A₁/(\(A^{*}\)₂)

giving your answer in exponential form

we know that \(A^{*}\)₂ is the complex  conjugate of A₂

so

\(A^{*}\)₂ = (6.403 ∠51.34° )*

= 6.403 ∠-51.34°

we convert to exponential form

A∠β can be written as A\(e^{j\beta }\)

\(A^{*}\)₂  = 6.403\(e^{-j51.34 }\)

also

A₁ = 6∠30

we convert to polar form

A₁ = 6\(e^{j30 }\)

so A₅ = A₁/(\(A^{*}\)₂)

A₅ = 6\(e^{j30 }\) / 6.403\(e^{-j51.34 }\)

A₅  = (6/6.403) \(e^{j(30+51.34) }\)

A₅  = 0.937\(e^{j81.34 }\)

Therefore A₅ in exponential form is 0.937\(e^{j81.34 }\)

Force is a kinetic quantity. Force = m x a. Hence, the mass of the body has an effect on force calculation.

Answer:

E = 132.69 sin(ωt -11.56)

i(t) = 6.64 sin (ωt +48.44) A

Explanation:

given data

e1 = 80 sin ωt volts                       80 < 0

e2 = 60 sin (ωt + π/2) volts          60 < 90

e3 = 100 sin (ωt – π/3) volts        100 < -60

solution

resultant will be  = e2 + e2 + e3

E =  80 < 0 + 60 < 90 + 100 < -60

\(\bar E\) = 80 + j60 + 50 - j50\(\sqrt{3}\)

\(\bar E\) = 130 + (-j26.60)

\(\bar E\) = 132.69  that is less than -11.56

so

E = 132.69 sin(ωt -11.56)

and

as we have given the impedance

z = (10-j17.3)Ω

z = 19.982 < -60

and

i(t) = \(\frac{132.69}{19.982}\) sin(ωt -11.56 + 60)  

i(t) = 6.64 sin (ωt +48.44) A

The acceleration components are independent of time, which indicates that the flow is steady. Answer: The acceleration components are\(a = -2aby(x^2 + y^2)^{-2}, b = -2bxy(x^2 + y^2)^{-2\).

The velocity components of u and v of a two-dimensional flow are given as follows:

u = ax + bx / x2 + y2, v = ay + by / x2 + y2

Calculate the acceleration. The velocity components for a two-dimensional flow field are given by

u = ax + bx / x2 + y2, v = ay + by / x2 + y2

From these velocity components, the acceleration components are obtained by differentiating the velocity components with respect to time. The time derivatives of u and v, respectively are as follows:du / dt = ∂u / ∂t + v ∂u / ∂y, dv / dt = ∂v / ∂t + v ∂v / ∂y

Acceleration is obtained by taking the time derivatives of velocity components with respect to time. The first time derivative of u with respect to t is given as follows:

∂u / ∂t = 0, since u does not depend on t. The other term in the time derivative of u is as follows:∂v / ∂y = ∂ / ∂y [(ay + by) / (x2 + y2)] = [(ay + by)(-2y)] / (x2 + y2)2= -2aby(x2 + y2)-2

Similarly, the time derivative of v with respect to t is as follows:∂v / ∂t = 0, since v does not depend on t. The other term in the time derivative of v is as follows:

∂u / ∂y = ∂ / ∂y [(ax + bx) / (x2 + y2)] = [(ax + bx)(-2y)] / (x2 + y2)2= -2bxy(x2 + y2)-2Hence, the acceleration components are as follows:a = du / dt = -2aby(x2 + y2)-2, b = dv / dt = -2bxy(x2 + y2)-2

The acceleration components can be expressed in terms of velocity components and their derivatives by using the continuity equation for incompressible flow as follows:∂u / ∂x + ∂v / ∂y = 0We can differentiate this equation with respect to time and use the equations of motion to obtain the following expression:

∂2u / ∂t2 + (u ∂u / ∂x + v ∂u / ∂y) = ∂2v / ∂t2 + (u ∂v / ∂x + v ∂v / ∂y) = 0

The acceleration components are given by the following expressions:

a = ∂u / ∂t + u ∂u / ∂x + v ∂u / ∂y, b = ∂v / ∂t + u ∂v / ∂x + v ∂v / ∂y

Thus, the acceleration components are given as follows:

a = -2aby(x2 + y2)-2, b = -2bxy(x2 + y2)-2

Therefore, the acceleration components are independent of time, which indicates that the flow is steady. Answer: The acceleration components are\(a = -2aby(x^2 + y^2)^{-2}, b = -2bxy(x^2 + y^2)^{-2\).

The total heat transfer rate from the plate to the air

Answer:

\(q=1.7845\)

Explanation:

From the question we are told that:

Air Temperature \(T_1=40c\)

Length \(l=2m\)

Velocity \(v=7m/s\)

Width \(w=0.5\)

Constant temperature \(T_t= 100C\)

Generally the equation for Total heat Transfer is mathematically given by

 \(q=hA(T_s-T_\infty)\)

Where

h=Convective heat transfer coefficient

 \(h=29.9075w/m^2k\)

Therefore

 \(q=h(L*B)(T_s-T_\infty)\)

When designing a set of simple test programs to determine the type compatibility rules of a C compiler to which you have access, it is important to consider the different data types that are used in C programming. An example of a set of test programs that can be used to determine the type compatibility rules of a C compiler:

Integer Test the compatibility of the C compiler with integer data types. It declares two variables of type int, initializes them with values, and then adds them together. The result is printed to the screen. If the program compiles and runs without any errors, then the C compiler is compatible with integer data types.

Floating-Point Test  the compatibility of the C compiler with floating-point data types. It declares two variables of type float, initializes them with values, and then adds them together. The result is printed to the screen. If the program compiles and runs without any errors, then the C compiler is compatible with floating-point data types.

By running the set of simple test programs described above, you can determine the type compatibility rules of a C compiler to which you have access.
