Answer:
COP_max = 18.69
Explanation:
We are given;
Heated space temperature; T_H = 26°C = 273K + 26 = 299K
Temperature at which heat is extracted; T_L = 10°C = 273 + 10 = 283K
Now the Coefficient of performance (COP) of a heat pump will be a maximum when the heat pump operates in a reversible manner. The COP of a reversible heat pump depends on the temperature limits in the cycle only and is determined by the formula;
COP_max = 1/(1 - (T_L/T_H))
Thus,
COP_max = 1/(1 - (283/299))
COP_max = 1/(1 - 0.9465)
COP_max = 1/0.0535 = 18.69
Answer:
The answer is "

Explanation:
Please find the complete question in the attached file.
Its change in temperature in pipes depends on rate heads and loss in pipes owing to pipe flow, contractual loss, etc.
The temperature change thus relies on V1 v2 p d D L.
if a pilot-operated check valve (POC) does not check flow, you will see The symptoms and symptoms of a failing swing test valve are regularly audible.
<h3>
What happens when the pilot valve reaches set strain?</h3>
When the pilot valve reaches set strain it opens and releases the strain from the dome. The piston is then unfastened to open and the principle valve exhausts the machine fluid. The manage pilot opens both to the principle valve exhaust pipe or to the atmosphere.
Pilot operated test valves paintings through permitting unfastened go with the drift from the inlet port thru the opening port. Supplying a pilot strain to the pilot port permits go with the drift withinside the contrary direction. Air strain on the pinnacle of the poppet meeting opens the seal permitting air to go with the drift freely.

And there's an equation to help determine which configurations will work best. In a four-stroke engine, an individual piston fires every 720 degrees (two crankshaft rotations). ... The flat-four fires at 180-degree intervals, and its V angle is 180 degrees, which leads to a balance of firing forces.Jan 14, 2011
