Answer:
a)
Calculate the net power developed by using
the following relation:
Wste=W-W.
Substitute 8728 kw for w, and 2846 kw for w..
Wyle=8728 - 2846
= 5882 kW
Therefore, the net power developed is 5882 kW).

Step 6 of 7 A
Calculate the thermal efficiency by using the
following relation:
Here, e, is the heat input.
Substitute w, for ..
w
Substitute s882 kw for ws and 8728 kw for w.
5882
1-8728
67.39%
Therefore, the thermal efficiency is 67.39%).
Comments (3)
Step 7 of 7 A
Calculate the back work ratio.
bwr =
Substitute 8728 kw for w, and 2846 kw for w..
bwr - 2846
bwr=8728
=0.326
Therefore, the back work ratio is 10.326).
Explanation:
Answer:
=> The total numbers of cylinders on the engine.
=> Total number of lobes in the cam ring.
=> The direction at which the cam ring rotates.
Explanation:
A cam is a kind of ring and a device that is being used in engines. One or the main purpose of using cams in engines us because it helps in the change or transformation of the rotational movement of the engine to a translational one. Instead of using a cam ring, a cam roller can be used in place.
There are three things that can be used to to determine the speed of cam ring speed and they are given below as;
=> The total numbers of cylinders on the engine.
=> The Total number of lobes in the cam ring.
=> The direction at which the cam ring rotates.
Answer:
Follow these five steps every time.
1.Wet your hands with clean, running water (warm or cold), turn off the tap, and apply soap.
2.Lather your hands by rubbing them together with the soap. Lather the backs of your hands, between your fingers, and under your nails.
3.Scrub your hands for at least 20 seconds. Need a timer? Hum the “Happy Birthday” song from beginning to end twice.
4.Rinse your hands well under clean, running water.
5.Dry your hands using a clean towel or air dry them.
The examples of engineering controls is Biohazard waste containers and Spill clean up kits.
What is engineering controls?
An engineering controls is a workplace process that protect workers by removing hazardous conditions or by placing a barrier between the worker and the hazard.
An example of engineering controls is installation of exhaust ventilation to remove airborne emissions to shield the worker.
Hence, the examples of engineering controls is Biohazard waste containers and Spill clean up kits.
Therefore, the Option C and D is correct.
