Answer:

  • increase
  • increase
  • decrease
  • decrease
  • increase
  • increase

Explanation:

EFFECT OF INCREASING THE BOLIER PRESSURE ON

  • pump work output ;  Increase
  • Turbine work output ; Increase
  • Heat supplied ; Decrease and this is because the latent heat been supplied will decrease when there is an increase in pressure
  • Heat Rejected ; Decrease
  • cycle efficiency ; Increase, the increase in the cycle efficiency increases in a very significant amount/rate because cycle efficiency = power output / heat input
  • Moisture content at Turbine exit ; Increases

The complete stress distribution obtained by superposing the stresses produced by an axial force and a bending moment is correct
Zanzabum

The complete stress distribution obtained by superposing the stresses produced by an axial force and a bending moment is correctly represented by F/A - (My)/(Iz).

<h3>What is the distribution of pressure at some stage in bending?</h3>

Compressive and tensile forces expand withinside the path of the beam axis beneath neath bending loads. These forces set off stresses at the beam. The most compressive pressure is observed on the uppermost fringe of the beam whilst the most tensile pressure is positioned on the decrease fringe of the beam.

The bending pressure is computed for the rail through the equation Sb = Mc/I, wherein Sb is the bending pressure in kilos in keeping with rectangular inch, M is the most bending second in pound-inches, I is the instant of inertia of the rail in (inches)4, and c is the space in inches from the bottom of rail to its impartial axis.

Please calculate the current for the circuit below
Aleks04 [339]

Answer:

The answer is "I = 0.0085106383 \ A"

Explanation:

Given:

R= 470  \ \Omega \\\\V= 4 \ v

Formula:

\to V=IR\\\\\to I = \frac{V}{R}\\\\

      = \frac{4}{470}\\\\ = 0.0085106383 \ A

What is the difference between a series circuit and a parallel circuit?
serg [7]

Answer:

In a parallel circuit, the voltage across each of the components is the same, and the total current is the sum of the currents flowing through each component. ... In a series circuit, every device must function for the circuit to be complete. If one bulb burns out in a series circuit, the entire circuit is broken.
