Answer: Technician A
Explanation: A coolant recovery system Is one of the most important part of a vehicles cooling system. When a coolant gets too hot, it forces it way out of the spring loaded radiator cap so as to relieve pressure. Any coolant which has escaped is recovered back through the discharge tube located in the recovery tank. The system is usually air free
Answer:
Recall the Entropy Balance (Second Law of Thermodynamics) equations for the system below
And for ideal gas, we know that
Change in Entropy of the air kJ/Kg.K, ΔS = S₁ - S
₂ = Cp Ln (T₂/T₁) - R Ln(P₂/P₁)
where R is gas constant =0.287kJ/kg.K and given
Cp=1.015 kJ/ kg.K
T₂ = 465k T₁=270k, P1=58kPa, P2=350kPa
substituting these values into the eqn above, we have
S = (1.015x 0.544) - (0.287x1.798)
S = 0.0363kJ/Kg.K
Hence, the mass specific entropy change associated with the compression process = 0.0363kJ/Kg.K
Brake system
Explanation: the engine doesn’t need to be running to make the brake system work the brake system it’s independent
Answer:
Number of cylinders of each gas
Explanation:
The Department of Transportation regulations Title 49 of the United States Code of Federal Regulations specifies that the number of cylinders of each gas being transported should be recorded on the shipping paper for gases classified under hazard class 2.2 of which one of them are the Non Flammable compressed gases.
The definition of gases in division 2.2 encompasses compressed gas, liquefied gas, compressed gas in solution, asphyxiant gas and oxidizing gas. They must meet the absolute pressure of 280kPa or greater at 20 degree Celsius.
