A fuel gas containing 45.00 mole% methane and the balance ethane is burned completely with pure oxygen at 25.00 degree C, and th
Dennis_Churaev [7]

Answer:

A)

- Q ( kw ) for vapor =  -1258.05 kw

- Q ( kw ) for liquid = -1146.3 kw

B )

- Q ( kj ) for vapor  = -1258.05 kJ

- Q ( KJ ) for liquid = - 1146.3 KJ

Explanation:

Given data :

45.00 % mole of methane

55.00 % of ethane

attached below is a detailed solution

A) calculate - Q(kw)

- Q ( kw ) for vapor =  -1258.05 kw

- Q ( kw ) for liquid = -1146.3 kw

B ) calculate  - Q ( KJ )

- Q ( kj ) for vapor  = -1258.05 kJ

- Q ( KJ ) for liquid = - 1146.3 KJ

since combustion takes place in a constant-volume batch reactor

Does a train have good sorce of power
Alexeev081 [22]

Answer: here you go sir

How trains work. On an electric locomotive, the wheels are moved by electric motors. ... On a diesel locomotive, a diesel engine drives the wheels via a mechanical transmission. Cutaway illustration of an electric power carHigh-speed trains are powered by electric current, collected from an overhead cable by a pantograph.

Explanation:

Chugging across short distances or entire continents, trains act as a major form of transportation worldwide. Also called railroads or railways, trains carry within their cars passengers or freight -- such as raw materials, supplies or finished goods -- and sometimes both.

Ivenika [448]

Answer:

correct answer is Both is same magnitude

Explanation:

given data

circle diameter = 10 mm

to find out

magnitude of the end deflection

solution

we know end deflection of cantilever is express as

end deflection of cantilever = \frac{PL^3}{3EI}    ......................1

so

moment of Inertia about any axis will be same for circular cross section

so that here Both will have same magnitude  with diameter 10 mm

so correct answer is Both is same magnitude

For an electric motor as a closed system, the rate of energy transfer in by electric current must equal the rate of power out th
neonofarm [45]

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.
