<h2>Symptom of Pneumatic Governor System</h2>

Explanation:

Engine speed will rise is right answer

Pneumatic Governor system that utilizations power from moving air delivered by pivoting flywheel blades to detect engine speed
Electronic Governor System Uses a limited point torque engine in place of the governor spring and -speed-sensing device utilized in a mechanical governor system
A governor is a system that is utilized to keep up the mean speed of a engine, inside specific cutoff points, under fluctuating burden conditions
It does this by managing and controlling the measure of fuel provided to the motor
Governors are likewise fitted in assistant diesel motors or generators, and alternators on the ship

A 100 MHz generator with Vg= 10/00 v and internal resistance 50 ohms air line that is 3.6m and terminated in a 25+j25 ohm load

Lilit [14]

The value of Vz at point z from the generator = 17.748 ∠ -107.62° V

Given data :

Internal resistance = 50 ohms

Vg = 10 ∠ 0° v

length of air line = 3.6 m

Terminating resistance = 25 + j25 Ω

First step : Determine the Total impedance 

Total Impedance ( z ) = Rin + Rline + Rl + jXl

= 50 + 50 + 25 + j25

= 125 + j25 ≈ 127.47 ∠ 11.3°

Next step : Determine the current in the circuit

current ( I ) = Vg / z

= ( 10∠0° v ) / ( 127.47 ∠ 11.3° )

= 0.0784 ∠ -11.3 amp

Final step : Determine the value of Vz at point z from the generator

Vz = ( Vg + I * Ri ) - ( RI * I + Rline * I )

= ( 10∠0° + 0.0784 ∠ -11.3 * 50 ) - ( 25 + j25 + 50 * 0.0784 ∠ -11.3 )

= -5.37 - j16.91 ≈ 17.748 ∠ -107.62° V

Hence we can conclude that the value of Vz at point z form the generator 17.748 ∠ -107.62° V

A mechanical system comprises three subsystems in series with reliabilities of 98, 96, and 94 percent. What is the overall relia

Westkost [7]

Answer:

<h2> The overall reliability of the system is 88%</h2>

Explanation:

When solving for the reliability of a complex machine, that is a machine that has more than one component, the reliability of the machine is the products of all individual components.

Given the

reliabilities of 98%,

96%, and

94%

Converting to decimals we have

98/100= 0.98

96/100= 0.96

94/100= 0.94

The product of all reliability is

0.98* 0.96 0.94= 0.88

now converting back to percent we have

0.88*100= 88%
