Answer:
Zero.
Explanation:
Lets take velocity V is given as in 2 dimensional flow
V=u i +v j
V=f(x,y)
u=f(x,y)
v=f(x,y)
Rotational ability ω given as
If
ω=0 ,then flow will be irrotational.
ω ≠0 ,then flow will be rotational.
So we can say that , ω will be zero every where for irrotational two dimensional flow .
I don’t see a drawing? Is there supposed to be a picture or something?
Answer:
Following are given the answers one-by-one with explanation:
(a) 8 records
As records are the horizontal rows of data and we have 8 of them.
(b) 5 fields
As fields are vertical columns of data and we have 5 of them.
(c)E3000
As by sorting Makers_names in ascending order the last one would be Rany and by sorting Processor_type we have two option with Rany that are B1500 and E3000. We can see that E3000 will come at the end.
(d) Computer_type
As only two choices (Laptop and PC ) are being used under the column computer_type so it can be amended to contain Boolean data.
(e) format check
This will check that the field should contain one alphabet (capital letter) followed by 4 digits each.
i hope it will help you!
Answer:
W=-940.36 KJ
Explanation:
Given that
Process follows pv=constant
So this is the isothermal process and work in isothermal process given as
Now by putting the values (1.4 bar =140 KPa)
W=-940.36 KJ
Negative sign indicates that this is a compression process and work will given to the system.
