Answer:
There is not enough information to answer this question. We don't even know if the blades are moving.
Explanation:
3. a 4. C im sure
Ex: done it
Explanation:
Expression for energy balance is as follows.
or,
Therefore,
Hence, expression for exit velocity will be as follows.
=
As for the given conditions is 1.007 kJ/kg K. Now, putting the given values into the above formula as follows.
=
= 40.7 m/s
Thus, we can conclude that velocity at the exit of a diffuser under given conditions is 40.7 m/s.
Answer:
204kW
Explanation:
P = t x ω = 500 x (2πx3900/60) = 204203W = 204kW
False
Voltage in an electrochemical cell is in indication of equilibrium, higher will be the non-equilibrium, higher will be the voltage, or we can say at equilibrium voltage tends to 0.
Voltage in an electrical cell is the result of flow of electron, which flow due to difference in charge of the cells, higher the charge difference higher will be the voltage, as the equilibrium between the chemical cells established the flow of electron will stop, and the voltage of the cell tend to 0.
