Explanation:
thank you for telling me that i have had people answer my question with a length and same happened to other peoples pages
Answer: Both Technicians
Explanation:
When testing a spring break it is advisable to Step on and off the brake, with the engine off, the parking brake knob is expected to pop out when air pressure falls between 20-40 psi.
Go under the vehicle and pull the spring brakes.
Turn on the engine back and pump the brake pedal down to the floor. To test the spring breaks
Answer:
Explanation:
First of all,we need to know what kind of research and how important it is before determining which computation method to use .
Then compare end result of research and cost of expensive methods .
Then we should opt for the best expensive method to be used for the given application.
Answer:
the required diameter is 0.344 m
Explanation:
given data:
flow is laminar
flow of carbon dioxide Q = 0.005 Kg/s
for flow to be laminar, Reynold's number must be less than 2300 for pipe flow and it is given as
arrange above equation for diameter
\frac{\rho Q D}{\mu A }<2300
dynamic density of carbon dioxide = 1.47× Pa sec
density of carbon dioxide is 1.83 kg/m³
D = 0.344 m
Answer:
False. Apart from heat loss, there are some other energy loss factors in electric motors.
They are:
(1) Core losses
(2) Windage losses
(3) Eddy Current
(4) Stray Load
Explanation:
STATOR RESISTANCE/HEAT LOSS(Heat loss I^2*R), which is the product of the square of the current multiplied by the resistance of the stator winding. The rotor also experiences I^2*R losses in the squirrel-cage rotor bars, called rotor resistance loss (rotor I^2*R).
CORE LOSSES also occur, originating in the lamination steel. Core losses include hysteresis losses, which result from reorientation of the magnetic field within the motor’s lamination steel, and eddy current losses resulting from electrical currents produced between laminations due to the presence of a changing magnetic field.
These electrical currents occur in both stator and rotor cores, but primarily in the stator, as these losses are proportional to the frequency of the current. The frequency of current in the rotor bars is only a small fraction of the line frequency, as the rotor current frequency is proportional to slip (the difference between operating speed and synchronous speed). Both the stator and rotor laminations have an insulated coating to reduce shorting losses (eddy current) from adjacent laminations.
Friction losses are from the motor bearings and lubrication.
WINDAGE LOSSES combine losses from the rotor spinning in air that creates drag and those from cooling fans used on the motor, along with friction losses in the bearings.
STRAY LOAD losses also are present.
