Answer:
Q = 62 MJ
Explanation:
given data
ideal gas mixture He = 3 kmol
ideal gas mixture Ar = 7 kmol
temperature t1 = 27°C = 300 K
pressure p1 = 200 kPa
solution
we apply here charle's law for pressure p constant that is
v ∝ T ..................1
and put here value we get
\frac{2v1}{v1} = \frac{t2}{300}
solve it we get
t2 = 600 K
so here mass of He is
mass = mole of He × molecular weight He
mass = 3 × 4
mass = 12 u
and
mass of Ar is
mass = mole of Ar × molecular weight Ar
mass = 7 × 40
mass = 280
and
heat supply will be
heat supply = mHe × CpHe × ΔT + mAr × CpAr × ΔT ................2
and here we use gas table and we get
CpHe = 5.19 (kJ/(kg K)) and CpAr = 0.5203 (kJ/(kg K))
put here value and we get
Q = 12 × 5.19 × 10³ (600-300) + 280 × 0.5203 × 10³ ( 600 -300 )
Q = 62 MJ
Answer:transmission
Explanation:
i’m not entirely familiar with this but i’m sure it’s transmission!
Answer:
Use cases are known to be a set of instruction or processes between a User/Actor with the system to produce a desired input.
With the aid of a diagram, the set of use cases that are carried out in this ATM are given below:
Insert PIN
(1)Perform required transaction
(2)Withdrawal
(3)Deposit
(4)Transfer
(5)Change PIN
(6)Exit
Note: Kindly find an attached diagram of the Use case as part of the solution to process carried out at the ATM
Sources: The diagram of the Use case for ATM was researched and taken from Quizlet.
Explanation:
Solution
Use cases are normally a set of instruction or processes between a User/Actor with the system to produce a desired input.
A use case diagram or image is a graphical representation of all the use case or processes that connects or interact with the system
The use case diagram is a part of Unified Modelling Language also called the UML.
The set of use cases that are carried out in this ATM use case diagram to know the requirements of the ATM is shown below:
- Insert PIN
- Perform required transaction
- Withdrawal
- Deposit
- Transfer
- Change PIN
- Exit
Now both the customer/client and Bank are seen as Actors.
Actors are the ones or people that interface with the system.
