Answer:

Exceeding the rated load for the circuit wiring causes the circuit breaker to trip, shutting off the power to the entire circuit. If there were no breaker in the circuit, an overload would cause the circuit wiring to overheat, which could melt the wire insulation and lead to a fire

Is a diesel truck less expensive to drive than a gas truck?

MArishka [77]

Answer:

Typically, diesel trucks cost more than those with gas engines, especially when you're first buying them, as diesel is usually featured as an add-on for gas-powered cars. Diesel add-ons can cost over $5,000 for midsize trucks and around $10,000 for heavy-duty trucks.

Answer:

mass flow=6.84kg/s

efficiency=73.5%

Explanation:

Hi!

To solve this problem follow the steps below, the procedure is attached in an image

1. Draw the complete outline of the problem.

2.Through laboratory tests, thermodynamic tables were developed, these allow to know all the thermodynamic properties of a substance (entropy, enthalpy, pressure, specific volume, internal energy etc ..)

through prior knowledge of two other properties such as pressure and temperature.

use thermodynamic tables to determine the following thermodynamic properties:

a. enthalpy at the turbine inlet

b. entropy at the turbine entrance

c. ideal enthalpy at the turbine outlet

d. real enthalpy at the turbine outlet

3. use the turbine efficiency equation and use the enthalpies found in step 2

uses the first law of thermodynamics that states that the energy that enters a system is the same that must come out, in this way we find the mass flow
