A gas turbine has a thermal efficiency of 20% and develops a power output of 8 MW. Determine the fuel consumption rate if heatin

AlexFokin [52]

Answer:

0.8 kilograms of fuel are consumed each second.

Explanation:

As turbines are steady-state devices, the thermal efficiency of a turbine is equal to the percentage of the ratio of the output power to fluid power, that is:

$\eta_{th} = \frac{\dot W}{\dot E} \times 100\,\%$

The fluid power is:

$\dot E = \frac{\dot W}{\eta} \times 100\,\%$

$\dot E = \frac{8\,MW}{20\,\%}\times 100\,\%$

$\dot E = 40\,MW$

Which means that gas turbine consumes 40 megajoules of fluid energy each second, which is heated and pressurized with help of the fuel, whose amount of consumption per second is:

$50\,\frac{MJ}{kg} = \frac{40\,MJ}{m_{fuel}}$

$m_{fuel} = 0.8\,kg$

0.8 kilograms of fuel are consumed each second.

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.
