Answer:
0.0280Kg/s
Explanation:
Given:
W = 1500
V2 = 300
V1 = 0
Q = 0 ( adiabatic)
T1 = 300
T2 = 20 m/s = converting to degrees we have 353°c
Let's use the energy equation

[/tex] m_• = W / (Cp(dT) + 0.5*V2^2) [/tex]


Answer:
A root-type supercharger works similar to that of an air pump. It pumps air into the intake of the engine. Within the engine cylinder, the compression of the air-fuel mixture takes place. A centrifugal supercharger, works like a turbo, compresses the air in it and then delivers it to the engine.
Answer:
The Decision Matrix
As you compare potential solutions to your design brief and the universal criteria for a good design, it may be obvious which solution is the best. ... A decision matrix is a chart with your requirements and criteria on one axis and the different solutions on the other.
Options: True or false
Answer:True, it will be called CRMWRONGEDLP.
Explanation:eNotes was founded in 1998 by Brad Satoris and Alexander Bloomingdale, to enable and enhance the ability of students to solve assignments as given and other home works,eNote is also used by students to prepare effectively and efficiently for examinations.
Since its launch eNote has been a great source of educational materials for students who have gained a lot in the use of its materials.
bullwhip effect is a concept in supply chain, where forcasts causes the supply chain to be inefficient, it usually starts from retailers who raise concern of high demands.
CRMWRONGEDLP, is the program that minimizes the bullwhip effects according to eNote.
Answer:
0.0297M^3/s
W=68.48kW
Explanation:
Hello! To solve this problem, we must first find all the thermodynamic properties at the input (state 1) and the compressor output (state 2), using the thermodynamic tables
Through laboratory tests, thermodynamic tables were developed, these allow to know all the thermodynamic properties of a substance (entropy, enthalpy, pressure, specific volume, internal energy etc ..)
through prior knowledge of two other properties such as pressure and temperature.
state 1
X=quality=1
T=-26C
density 1=α1=5.27kg/m^3
entalpy1=h1=234.7KJ/kg
state 2
T2=70
P2=8bar=800kPa
density 2=α2=31.91kg/m^3
entalpy2=h2=306.9KJ/kg
Now to find the flow at the outlet of the compressor, we remember the continuity equation that states that the mass flow is equal to the input and output.
m1=m2
(Q1)(α1)=(Q2)(α2)

the volumetric flow rate at the exit is 0.0297M^3/s
To find the power of the compressor we use the first law of thermodynamics that says that the energy that enters must be equal to the energy that comes out, in this order of ideas we have the following equation
W=m(h2-h1)
m=Qα
W=(0.18)(5.27)(306.9-234.7)
W=68.48kW
the compressor power is 68.48kW
