Find the corresponding airplane velocities and drags if only fluid compressibility is important and the airplane is flying in the U.S. Standard Atmosphere at 30,000 ft. Assume that the air is an ideal gas.
Answers
The corresponding airplane velocity is found to be 236.1 m/s and the drag force on the airplane is 39973 N.
According to the question, we need to find the corresponding airplane velocities and drags if only fluid compressibility is important and the airplane is flying in the U.S. Standard Atmosphere at 30,000 ft. Assume that the air is an ideal gas. Fluid compressibility is important only when the flow velocity is near or above the speed of sound. It affects the amount of drag experienced by an airplane. In this case, the airplane is flying in the U.S. Standard Atmosphere at 30,000 ft. The air is an ideal gas.
At 30,000 ft, the density of the air is ρ = 0.36 kg/m³, and the temperature is T = 223 K. We will use the U.S. Standard Atmosphere values for the specific gas constant R of air, 287.1 J/(kg·K). The speed of sound in air at 30,000 ft can be found using the formula, where γ is the ratio of specific heats and can be assumed to be 1.4 for air. So the speed of sound at 30,000 ft is a = 295.1 m/s. This is the threshold velocity beyond which fluid compressibility becomes important.
According to the problem, we are only interested in the velocities close to the speed of sound. Therefore, we can take the velocity of the airplane to be 0.8a = 236.1 m/s. At this velocity, fluid compressibility becomes important. The drag force on the airplane can be calculated using the formula, where Cd is the drag coefficient, ρ is the density of the air, v is the velocity of the airplane, and A is the reference area of the airplane.
To calculate the drag coefficient Cd, we need to know the shape of the airplane. For a typical airplane, Cd can be assumed to be 0.02 at low speeds and to increase with velocity. At the velocity of 236.1 m/s, Cd can be assumed to be 0.1. The reference area A can also be assumed to be 25 m² for a typical airplane. Substituting the values in the formula, we get,
Fd = 0.5 × 0.1 × 0.36 × (236.1)² × 25 = 39973 N.
Therefore, the drag force on the airplane is 39973 N.

Answers
An extremum is a point where the function has its highest or lowest value, and at which the slope is zero.
The dimensions to be used if the volume is fixed and the cost of construction is to be kept to a minimum is as follows;
Height of cylinder = 2 × Radius of cylinderReason:
The given parameters are;
Form of silo = Cylinder surmounted by a hemisphere
Cost of construction of hemisphere per square unit = 2 × The cost of of construction of the cylindrical side wall
Required:
The dimensions to be used if the volume is fixed and the cost of construction is to be kept to a minimum
Solution:
The fixed volume of the silo, V, can be expressed as follows;
\(V = \pi \cdot r^2 \cdot h + \dfrac{2}{3} \cdot \pi \cdot r^3\)
\(h = \dfrac{V - \dfrac{2}{3} \cdot \pi \cdot r^3 }{\pi \cdot r^2 }\)Where;
h = The height of the cylinder
r = The radius of the cylinder
The surface area is, Surface Area = 2·π·r·h + 2·π·r²
The cost, C = 2·π·r·h + 2×2·π·r² = 2·π·r·h + 4·π·r²
Therefore;
\(C = 2 \times \pi \times r\times \dfrac{V - \dfrac{2}{3} \cdot \pi \cdot r^3 }{\pi \cdot r^2 } + 4 \cdot \pi \cdot r^2 = \dfrac{8 \cdot r^3 \cdot \pi + 6 \cdot V}{3 \cdot r}\)
\(C = \dfrac{8 \cdot r^3 \cdot \pi + 6 \cdot V}{3 \cdot r}\)At the minimum value, we have;
\(\dfrac{dC}{dr} =0 = \dfrac{d}{dr} \left(\dfrac{8 \cdot r^3 \cdot \pi + 6 \cdot V}{3 \cdot r} \right) = \dfrac{16 \cdot r^3 \cdot \pi - 6 \cdot V}{3 \cdot r^2}\)Which gives;
16·π·r³ = 6·V
\(V = \dfrac{16 \cdot \pi \cdot r^3}{6} = \dfrac{8 \cdot \pi \cdot r^3}{3}\)Which gives;
\(h = \dfrac{\dfrac{8 \cdot \pi \cdot r^3}{3} - \dfrac{2}{3} \cdot \pi \cdot r^3 }{\pi \cdot r^2 } = 2 \cdot r\)
h = 2·r
The height of the silo, h = 2 × The radius, 2
Therefore, the dimensions to be used if the volume is fixed and the cost is to be kept to a minimum is, height, h = 2 times the radius

Final Temperature \(T_2=250pisa =114.94F\)
Efficiency \(E=75\%=0.75\)
Generally the equation for Work-done is mathematically given by
\(W=\int C_pT\)
\(W=10.03(114.94-70 )+0.0184((114.94)^2-70^2 )\)
\(W=527.21btu/ibmole\)
\(W=11.982btu/ibm\)
Generally the equation for Efficiency is mathematically given by
\(E=\frac{isotropic Power}{Actual P'}\)
\(E=\frac{P}{P'}\)
Since
Isotropic Power
\(P=0.0167*11.982btu/ibm\)
\(P=0.2btu/s\)
Therefore
\(P'=\frac{0.2}{0.75}\)
\(P'=0266btu/s\)
Since
\(1btu/s=1.4148hp\)
Therefore
\(P'=0.377hp\)

A farmers drainage ditch has a width of 2 m and a depth of 50 cm. It is lined with concrete with a roughness of 0.011 and slopes at 0.0009. Calculate the ditch's discharge rate.
Answers
Answer:
Using the Manning's Equation, the discharge rate can be calculated as follows:
Q = (1.49/n) x A x R^(2/3) x S^(1/2)
Where:
Q = discharge rate (m^3/sec)
n = Manning's roughness coefficient (0.011)
A = cross sectional area of the ditch (2m x 0.5m = 1 m^2)
R = hydraulic radius (half the width of the ditch, or 1 m)
S = slope of the ditch (0.0009)
Q = (1.49/0.011) x 1m^2 x 1m^(2/3) x 0.0009^(1/2)
Q = 13,636.36 m^3/sec

The water is continuously pumped into the chamber where it is irradiated with UV light before it exits through the the appropriate tube into a collection vessel. The disinfection rate constant rate of disinfection with UV light is 7.80 s.1 and the amount of bacteria has to be reduced by 99.9%. be reduced by 99.9%. Since the Army requires an object that can be carried in a backpack, it requires that the chamber of the apparatus must not hold a capacity greater than 2 L. How much water will the system be able to produce during 10 hours of sunshine?
Answers
Solution :
The treatment system will operate as the well mixed chamber.
Disinfection rate constant for the UV light, k is 7.80 /s. Number of bacteria in water need to be reduced by 99.9%
Percent reduction of bacteria should be \($(1-10^{0.99}) \times 100 =89.7\%$\)
Volume of the unit chamber is fixed at 2L
Assume the inlet concentration, \($C_0$\) as 1000
The outlet concentration of bacteria, C should be \($1000-\left(1000 \times \frac{89.7}{100}\right)$\)
= 103
The well mixed chamber will then follow a completely mixed flow reactor model.
Compute the time required :
\($t=\frac{1}{k}\left(\frac{C_0}{C}-1\right)$\)
\($t=\frac{1}{7.8}\left(\frac{1000}{103}-1\right)$\)
= 1.115 s
Flow through the system is \($\frac{2 \ L}{1.115 \ s}$\) = 1.79 L/s
The amount of water treated during the 10 hours of sunlight is 1.79 x 10 x 60 x 60 = 64440 L

Answers
Televisions, toasters, and blow dryers are typically made to run on different voltage requirements. Televisions generally run on 110-120 volts in North America and 220-240 volts in other regions. Toasters and blow dryers commonly operate on 110-120 volts.
The voltage requirements for electrical appliances vary depending on the region and the specific appliance. In North America, the standard voltage for household outlets is 110-120 volts. Therefore, televisions, toasters, and blow dryers designed for use in North America are typically made to run on this voltage range.
In other regions, such as Europe and many other parts of the world, the standard voltage for household outlets is 220-240 volts. Televisions manufactured for use in these regions are designed to operate on this higher voltage range.
However, it's important to note that there can be variations and exceptions. Some appliances, especially those designed for travel or international use, may have dual voltage capabilities, allowing them to be used with both 110-120 volts and 220-240 volts.
In general, it is always recommended to check the voltage requirements specified by the manufacturer for each specific appliance to ensure safe and proper operation.
