Answer:
Explanation:
The adiabatic throttling process is modelled after the First Law of Thermodynamics:
Properties of water at inlet and outlet are obtained from steam tables:
State 1 - Inlet (Liquid-Vapor Mixture)
State 2 - Outlet (Superheated Vapor)
The change of entropy of the steam is derived of the Second Law of Thermodynamics:
Answer:
Efficient when the marginal benefits of project = marginal costs of project.
Explanation:
Majority Decision Rule:
Majority decision rule is based on the notion of equality. An alternative is selected which has majority of votes. The simple majority decision rule may generate efficient results if the marginal benefits of a project are equal or greater than the marginal costs of the project.
I think because if you’ve already turned it in they might as well grade asap instead of waiting
Answer:
The right solution is "2625 kN".
Explanation:
According to the question,
The average pressure will be:
= 
By putting values, we get
= 
= 
= 
hence,
The average force will be:
= 
= 
= 
Or,
= 
Answer:
McDonald’s announced recently that they are going through some major menu changes, and will be nixing some unnecessary ingredients.
