Answer:
33.4KW
Explanation:
Firstly, we calculate the power index in a reversible heat engine which is given as;
n = 1 - T1/T2
T1 = atmospheric temperature 298k
T2 = reservoir temperature 1500k
n = 1 - 298/1500
n = 0.8013
output energy = n × energy input
0.8013×150000 = 120195KJ/hr
Power output = 120195KJ/hr/3600 = 33.4KW
Answer:
123.9 Btu
Explanation:
The energy balance on the air is:
∆E = E2 − E1 = ∆KE + ∆PE + ∆U = Q + W
ignore ∆KE and ∆PE,
W = ∆U − Q = m(u2 − u1) − Q; (u2 − u1 = 51.94 Btu/lb)
ideal gas properties is attached
W = (2 lb)(143.98 − 92.04) Btu/lb − (− 20 Btu) = 123.9 Btu
u2 − u1 ≈ cv(T2 − T1) = (0.173 Btu/lb°R)(840 − 540)
°R = 51.9 Btu/lb
Answer:
Heat
Explanation:
Carnot cycle:
Carnot cycle is the ideal cycle for all working engine .Carnot cycle all processes are reversible.It have fore process Out of two are constant temperature process and other two are isentropic process(reversible adiabatic).
We know that area under T-s diagram represents the heat.
So 
From cycle we can say that
A effective ground-fault current path is an intentionally constructed, low-impedance electrically conductive path designed and intended to carry current during ground-fault conditions from the point of grounding on a wiring system to the electrical supply source.
<h3>Is earth an effective ground fault current path?</h3>
- Sticking the wire in the ground is not sufficient since the earth is not thought to be a reliable ground-fault current channel.
- The electrical system of a building or other structure is based on grounding.
- To give a fault current a secure path to travel, grounding is used.
- When installing switches, light fixtures, appliances, and receptacles, a complete ground route must be kept.
- The undesired current flow trips circuit breakers or blows fuses in a system that is correctly grounded.
- Through the use of a grounding bank, effective grounding maintains voltages within predetermined limits during a line-to-ground fault (short-circuit condition).
