Answer:
2
Explanation:To find the solution we must first make the transformations to international units,
In this way:
Inches of length (L) to feet =
So we can identify the area by hour:
Once the area is identified, we now identify the number of passes required,
Passes required = Area x number of passes
We transform speed to international units
So we can identify the covered area
where
m = drum widht
p = efficiency
In this way we obtain the number of rollers given by:
No. of Rollers = Passes required / covered area
No of rollers = 48136/40269
No of rollers = 1.19, that is, 2

The specific enthalpies at inlet and outlet are, respectively:
Inlet (Superheated Steam)

Outlet (Liquid-Vapor Mixture)

The power produced by the turbine is:



Answer:
Rack and Pinion Steering Rack and pinion steering transmits circular motion from the steering wheel to a pinion that meshes with teeth on a flat rack. ... Suspension Systems The suspension system supports the vehicle, allowing the wheels to move up and down over irregularities in the road.
Answer:
a. $79,122.50
b. 314. 84 miles.
c. 700 ways.
Explanation:
a. Compound interest = A = P (1 + r/n)nt ;
where P = 7500 (principal amount)
r = 15% (interest rate)
t = 16 (no of years)
n = 4 (no of times compounded annually.)
and finally A is the Amount (present value after 16 years)
Upon calculation A = $79,122.50.
b. Answer: 314. 84 miles.
Explanation:
Given data. 160 miles / 7.75 liters of gasoline
Therefore 1 liter of gasoline = 160/7.75 = 20.645 miles/ liter.
15.25 liters of gasoline = 20.645 * 15.25 = 314.84 miles.
c. Answer: 700 ways.
Explanation:
This is an application of generalized principle of counting.
4 Americans can be choosen from 7 Americans = 7C4 = 35
3 Russians can be choosen from 6 Russians = 6C3 = 20.
Total number of ways = (7C4)* (6C3) = 35 * 20 = 700 ways.
Answer:
Penetration testing
<h3>
What is Penetrating Testing?</h3>
- A penetration test, colloquially known as a pen test or ethical hacking, is an authorized simulated cyberattack on a computer system, performed to evaluate the security of the system; this is not to be confused with a vulnerability assessment.
