Answer:

The transportation and logistics workplaces includes;

1) Vehicles

2) Warehouses

3) Airports

4) Bus and train terminals

Explanation:

Transportation is the process involved in the movement of goods, product, materials and people from place to place, including the parts movement to the areas where they are assembled so that they can be assembled

Logistics is the management process of products and personnel delivery to a customer designated point at the required time, consisting of the required quantities, in the right condition at the correct charging price.

An automotive fuel has a molar composition of 85% ethanol (C2H5OH) and 15% octane (C8H18). For complete combustion in air, deter

slava [35]

Answer:

a) 1

b) 1813.96 MJ/kmol

c) 32.43 MJ/kg , 1980.39 MJ/Kmol

Explanation:

molar mass of ethanol (C2H5OH) = 46 g/mol

molar mass of octane (C8H18) = 114 g/mol

therefore the moles of ethanol and octane

ethanol = 0.85 / 46

octane = 0.15 / 114

a) determine the molar air-fuel ratio and air-fuel ratio by mass

attached below

mass of air / mass of fuel = 12.17 / 1 = 12.17

b ) Determine the lower heating value

LHV of ( C2H5OH) = 26.8 * 46 = 1232.8 MJ/kmol

LHV of (C8H18). = 44.8 mj/kg * 114 kg/kmol = 5107.2 MJ/Kmol

LHV ( MJ/kmol) for fuel mixture = 0.85 * 1232.8 + 0.15 * 5107.2 = 1813.96 MJ/kmol

c) Determine higher heating value ( HHV )

HHV of (C2H5OH) = 29.7 * 46 = 1366.2 MJ/kmol

HHV of C8H18 = 47.9 MJ/kg * 114 = 5460.6 MJ/kmol

HHV in MJ/kg = 0.85 * 29.7 + 0.15 * 47.9 = 32.43 MJ/kg

HHV in MJ /kmol = 0.85 * 1366.2 + 0.15 * 5460.8 = 1980.39 MJ/Kmol

Write a function called largest3 which takes 3 numbers as parameters and returns the largest of the 3. Write a program which tak

tamaranim1 [39]

Answer:

The solution code is written in Python.

def largest3(num1, num2, num3):
largest = num1
if(largest < num2):
largest = num2
if(largest < num3):
largest = num3
return largest
first_num = int(input("Enter first number: "))
second_num = int(input("Enter second number: "))
third_num = int(input("Enter third number: "))
largest_number = largest3(first_num, second_num, third_num)
print("The largest number is " + str(largest_number))

Explanation:

Create function largest3

Firstly, we can create a function largest3 which take 3 numbers (num1, num2, num3) as input. (Line 1).
Please note Python uses keyword def to denote a function. The code from Line 2 - 10 are function body of largest3.
Within the function body, create a variable, largest, to store the largest number. In the first beginning, just tentatively assign num1 to largest. (Line 2)
Next, proceed to check if the current "largest" value smaller than the num2 (Line 4). If so, replace the original value of largest variable with num2 (Line 5).
Repeat the similar comparison procedure to num3 (Line 7-8)
At the end, return the final value of "largest" as output

Get User Input

Prompt use input for three numbers (Line 13 -15) using Python built-in input function.
Please note the input parts of codes is done outside of the function largest3.

Call function to get largest number and display

We can simply call the function largest by writing the function name largest and passing the three user input into the parenthesis as arguments. (Line 17)
The function largest will operate on the three arguments and return the output to the variable largest_number.
Lastly, print the output using Python built-in print function. (Line 18)
Please note the output parts of codes is also done outside of the function largest3.

Some designers suggest that speech recognition should be used in a telephone menu system. This would allow users to interact wit

Ghella [55]

The designers suggest that speech recognition allows for spoken interaction or conversation and spoken prompts or commands.

Explanation:

The speech recognition is used when the user has physical impairments and hands are busy, eyes are occupied and the user cannot read.

We can save time with the usage of speech recognition system. The users are knowledgeable based on the actions available.

The problems faced in speech recognition system are in the noisy environment it has bad microphones and the commands should be learned and remembered.

The other obstacle is error correction is time consuming. the speech production has slow space to speech output provides privacy in public spaces. The disadvantage is it contains large amount of information.

What is "Engineering"?

Liono4ka [1.6K]

Engineering is when both the application of science and math are used to solve problems. An engineer is a person who designs, builds, or maintains engines, machines, or public works. There are six large branches of engineering such as Mechanical, Chemical, Civil, Electrical, Management, and Geotechnical, they all have hundreds of subcategories of engineering under each different branch.
