Inside was the news that Jilt Nord, a state-owned coal mine, planned to expand and the people of Runcurel would lose their homes and land.
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 .
Answer:
Carbon dioxide temperature at exit is 317.69 K
Carbon dioxide flow rate at heater exit is 20.25 m³/s
Explanation:
Detailed steps are attached below.
Answer:
2543 k
Explanation:
This problem can be resolved by applying the first law of thermodynamics

attached below is a detailed solution
cp = 1200
Answer:
The objective of a properly proportioned concrete mix are:
- To produce the combination of cementitious material, water, and aggregate that meets the requirements of a particular structure, portion of a structure, or series of structures at least cost.
- To produce concrete of the specified properties.
- To produce a satisfactory of end product, such as beam, column or slab as economically as possible.
