Answer:
Mass of cement used is 62.5 lb
Mass of gravel used is 225 lb
Explanation:
The ratio given here is cement to sand to gravel = 1 : 2.4 : 3.6
So, for 150 lb of sand
C : S : G = 1 : 2.4 : 3.6
Mass of cement used is 62.5 lb
Mass of gravel used is 225 lb
Answer:
11548KJ/kg
10641KJ/kg
Explanation:
Stagnation enthalpy:
given:
cp = 1.0 KJ/kg-K
T1 = 25 C +273 = 298 K
V1 = 150 m/s
Answer: 11548 KJ/kg
Using Heat balance for steady-state system:
Qin = 42 MW
W = -100 KW
V2 = 400 m/s
Using the above equation
Answer: 10641 KJ/kg
c) We use cp because the work is done per constant pressure on the system.
