Answer:
Because these subsystems interact with each other and the biosphere, they work together to influence the climate and make an affect on life all over the Earth.
Administrative law is part of the so called ‘public law’. It is the ‘common’ law of the public administration and it is broadly a statutory law. The administrative legal system collects concepts and institutions from other legal systems such as civil law, criminal law, or even labour law. In addition, it is self-sufficient; there is no need to bring rules from other areas of law to fill in the gaps.
Answer: An engineer or a craftsperson
Explanation:
Welding symbols allow the engineer or draftsperson to communicate detailed information about the weld to the welder. In most cases, the welding symbol has an arrow, which points to the location on the drawing where a weld is required. The arrow is attached to a leader line that intersects with a horizontal reference line. The arrow and leader line point to the joint in question, while the weld symbol tells the welder what type of weld to do. If the weld symbol is below the reference line, the weld should be made on the same side as the arrow.
Answer:
Explanation:
Given that:
Superheated vapor enters the turbine at 10 MPa, 480°C,
From the tables of superheated steam tables; the following values are obtained
Also; from the system, the isentropic line is 1-2 in which s_2 is in wet state
From the values obtained;
Therefore;
6.52846 = 0.51624+7.82x
6.52846 - 0.51624 = 7.82 x
6.01222 = 7.82 x
x = 6.01222/7.82
x = 0.7688
The enthalpy for this process at state (s_2) can be determined as follows:
The actual enthalpy at s_2 by using the isentropic efficiency of the turbine can determined by using the expression:
kJ/kg
The work pump is calculated by applying the formula:
However;
From the process;
The actual enthalpy at s_4 by using the isentropic efficiency of the turbine can determined by using the expression:
Answer:
I think option d is the answer
