or,
We have that the relationships between users and per missions defined is given as
a) The relationship may <u>want </u>to be described as o(n p u x).(5)
b) he <em>relationship </em>ought to be described as o(n*s*u*x).
<h3>DAC scheme & RBAC scheme</h3>
a)
Generally, The relationship may <u>want </u>to be described as o(n*p*u*x)
X is a random cost, structured greater on organizational shape and culture.
b)
Finally, the relationship ought to be described as o(n*s*u*x).
X here is some possibly random fee, established greater on organizational shape and culture
is the wide variety of structures that manipulate their personal roles

Answer:
a) 4.1 kw
b) 4.68 tons
c) 4.02
Explanation:
Saturated vapor enters compressor at ( p1 ) = 2.6 bar
Saturated liquid exits the condenser at ( p2 ) = 12 bar
Isentropic compressor efficiency = 80%
Mass flow rate = 7 kg/min
A) Determine compressor power in KW
compressor power = m ( h2 - h1 )
= 7 / 60 ( 283.71 - 248.545 )
= 4.1 kw
B) Determine refrigeration capacity in tons = m ( h1 - h4 )
= 7/60 ( 248.545 - 107.34 )
= 16.47 kw = 4.68 tons
C) coefficient of performance ( COP )
= Refrigeration capacity / compressor power
= 16.47 / 4.1 = 4.02
