Answer:
The source temperature is 1248 R.
Explanation:
Second law efficiency of the engine is the ratio of actual efficiency to the maximum possible efficiency that is reversible efficiency.
Given:
Temperature of the heat sink is 520 R.
Second law efficiency is 60%.
Actual thermal efficiency is 35%.
Calculation:
Step1
Reversible efficiency is calculated as follows:
Step2
Source temperature is calculated as follows:
T = 1248 R.
The heat engine is shown below:
Thus, the source temperature is 1248 R.
The Occupational Safety and Health Administration's (OSHA) Hazard Communication Standard (HCS) I think
Answer: False
Explanation: The process in which the thickness of a material is reduced with help of two rolls opposing each other it is called as rolling.It is a type of deformation technique that is done on work piece by using compressive forces exerted by rolls working in the opposite direction of reach other. A draft get created in this process which has the difference of initial and final thickness of work piece. Thus, the statement given is false.
