  • Social Media
  • SMS Text Messaging
  • Email Marketing
  • Direct Email
  • Voice Calling

<h3>What is a communication?</h3>

This means the act of giving, receiving and sharing of information as well as talking, writing, listening or reading.

The types of Communication includes:

  • Verbal Communication: It occurs when we engage in speaking with others.
  • Non-Verbal Communication: It occurs when what we speak often says more than the actual words.
  • Written Communication: It occurs in an actual text or writing.
  • Listening: It occurs when we pay attention to a speaker.

The wired communication involves transmission of data over a wire-based communication technology while a wireless communication involves transmission of data without the use of a cable or wire.

Compute the thermal efficiency for an ideal gas turbine cycle that operates with a pressure ratio of 6.75 and uses helium gas.
pychu [463]

Solution:

Given:

pressure ratio, r_{p} = 6.75

Formula used:

\eta = \frac{(r_{p})^{\frac{\gamma -1}{\gamma}}-1}{r_{p}^{\frac{\gamma-1}{\gamma}}}\\

\eta = 1- \frac{1}{r_{p}^{\frac{\gamma-1}{\gamma }}}         (1)

where,

r_{p} = pressure ratio

γ = specific heat ratio of a gas( here, helium gas it is 1.667)

Now,

Eqn (1 ) is for thermal efficiency of an ideal gas, using eqn (1), we get

\eta = 1- \frac{1}{6.75^{\frac{\ 1.667-1}{\ 1.667 }}}

\eta = 1- \frac{1}{2.1469} = 0.5342

percentage thermal efficiency, \eta =53.42%

Explain how you would solve for total resistance in a parallel circuit versus a series circuit. How would you apply and solve fo
Mekhanik [1.2K]

Answer:

No, series parallel, as it implies has components of the circuit configured in both series and parallel. This is typically done to achieve a desired resistance in the circuit. A parallel circuit is a circuit that only has the components hooked in parallel, which would result in a lower total resistance in the circuit than if the components were hooked up in a series parallel configuration.
