Answer:

22.86%

Explanation:

To get the overall efficiency of the process, we simply get the product of the given efficiencies.

Therefore, overall efficiency of the process=Crude production efficiency* Transportation efficiency* Refining efficiency* Distribution of gasoline efficiency*  Engine efficiency efficiency

Overall efficiency=0.93*0.92*0.94*0.97*0.293*100%=22.85798714 %

Approximately, the overall efficiency of the process is 22.86%

Sergio [31]

Answer:

676 ft

Explanation:

Minimum sight distance, d_min

d_min = 1.47 * v_max * t_total where v_max is maximum velocity in mi/h, t_total is total time

v_max is given as 50 mi/h

t_total is sum of time for right-turn and adjustment time=8.5+0.7=9.2 seconds

Substituting these figures we obtain d_min=1.47*50*9.2=676.2 ft

For practical purposes, this distance is taken as 676 ft

A gas cylinder is connected to a manometer that contains water. The other end of the manometer is open to the atmosphere, which
horrorfan [7]

Answer: the absolute static pressure in the gas cylinder is 82.23596 kPa

Explanation:

Given that;

patm = 79 kPa, h = 13 in of H₂O,

A sketch of the problem is uploaded along this answer.

Now

pA = patm + 13 in of H₂O ( h × density × g )

pA= 79 + (13 × 0.0254 × 9.8 × 1000/1000)

pA = 82.23596 kPa

the absolute static pressure in the gas cylinder is 82.23596 kPa

likoan [24]

Answer:

  2.455 W

Explanation:

The power dissipated in each branch is ...

  P = V^2/R

So, the branch powers are ...

  branch 1: 18^2/220 ≈ 1.473 W

  branch 2: 18^2/330 ≈ 0.982 W

Total power is ...

  1.473 W + 0.982 W = 2.455 W

A defective crankshaft position sensor is a common cause of a no-start condition.
ohaa [14]

Answer:

Switching on and off

Explanation:

No starters are often caused by a faulty crankshaft actuator. The signals from this transmitter is sent to the ignition module, which turns in and out of the ignition system. If you already have an RPM sign, it's possible that a faulty ignition unit or PCM isn't turning the coils on and off. Along with button on and the motor cranking, testing for volts at the contacts with a voltmeter.
