Answer: 150m
Explanation:
The following can be depicted from the question:
Dimensions of outer walls = 9.7m × 14.7m.
Thickness of the wall = 0.30 m
Therefore, the plinth area of the building will be:
= (9.7 + 0.30/2 + 0.30/2) × (14.7 × 0.30/2 + 0.30/2)
= 10 × 15
= 150m
Answer:
The mass flow rate of jet =69.44 kg/s
Explanation:
Given that
velocity of jet v= 60 m/s
Power P=250 KW
As we know that force offered by water F

Power P= F.v
So now power given as

We know that mass flow rate = ρAv

250 x 1000 = mass flow rate x 3600
mass flow rate = 69.44 kg/s
So the mass flow rate of jet =69.44 kg/s
Answer:
(1) , (2) , (4) ,(6).
Explanation:
Use of casting process:
1.When the size of the mold is more or we can say that when the size of casting is more.
2.When the mechanical strength of the casting product is not important.
3.When the required ductility of the product is not to high .Generally casting product is more brittle with high strength.
4.Generally cost of casting product is not too high or we can say that casting product is economically.
Therefore the following options are correct -
(1) , (2) , (4) ,(6).
