The total present worth is $19,783.01
The present worth of a series of cash flow is the value of the cash flows in year 0 (today)
Cash flow in year 0 = 5330
Cash flow in year 1 = 0
Cash flow in year 2 = 0
Cash flow in year 3 = 13075 / (1.02)^3 = 12,320.86
Cash flow in year 4 = 2308 / (1.02)^4 = 2,132.24
Present worth = $19,783.01

Aviation refers to flying using an aircraft, like an aeroplane. It also includes the activities and industries related to flight, such as air traffic control. The biggest of the many uses of aviation are in air travel and military aircraft . The main difference between aeronautics and aviation is their focus. Aeronautics involves the study of the science, design, and manufacture of flying vehicles while aviation involves flying or operating an aircraft and various activities surrounding mechanical flight and the aircraft industry

<h2>Generator </h2>
Explanation:
A generator converts mechanical energy into electrical energy
Answer:
The critical length of surface flaw = 6.176 mm
Explanation:
Given data-
Plane strain fracture toughness Kc = 29.6 MPa-m1/2
Yield Strength = 545 MPa
Design stress. =0.3 × yield strength
= 0.3 × 545
= 163.5 MPa
Dimensionless parameter. Y = 1.3
The critical length of surface flaw is given by
= 1/pi.(Plane strain fracture toughness /Dimensionless parameter× Design Stress)^2
Now putting values in above equation we get,
= 1/3.14( 29.6 / 1.3 × 163.5)^2
=6.176 × 10^-3 m
=6.176 mm
