Answer:
2.0%
Explanation:
Percentage of aggregate = 94%
Specific gravity = 2.65
Specific gravity of asphalt = 1.9
Density of mix = 147pcf = 147lb/ft³
Total weight of mix: (volume = 1ft³)
= (147lb/ft³)(1ft³)
= 147lb
Percentage weight of asphalt in<u> mix:</u>
100% - 94%
= 6%
Weight of asphalt binders
= 6% x 147lb
= 8.82lb
Weight of aggregate in mix:
= 94% x 147
= 138.18lb
Specific weight of asphalt binder:
(Gab)(Yw)
Yw = specific Weight of water
= 62.4lb
Gab = specific gravity of asphalt binder
= 1.0
(62.4lb)(1.0)
= 62.4 lb/ft³
Volume of asphalt in binder:
8.82/62.4
= 0.14ft³
Specific weight of binder in mix:
2.65 x 62.4lb/ft³
= 165.36 lb/ft³
Volume of aggregate:
= 138.18/165.36
= 0.84ft³
Volume of void in the mix:
1ft³ - 0.84ft³ - 0.14ft³
= 0.02ft³
<u>The percentage of void in total mix:</u>
VTM = (0.02ft³/1ft³)100
= 2.0%
Answer:
W = 31.393 Btu
Explanation:
given data
piston-cylinder assembly contains water = 0.5 lb
p1 = 40 lbf/in² = 40 × 144 lbf/ft²
T1 = 300° F
p2 = 14.7 lbf/in² = 14.7 × 144 lbf/ft²
pv 1.2 = constant.
solution
we use here superheated table A 4E to get value for p1 = 40 and t = 300
v1 = 11.04 ft³/lbm
so we know
,...............1
solve it we get
v2 = 25.425 ft³/lbm
and here
W = 
...............2
put here value we get
W = 
solve it we get
W = 31.393 Btu
Answer:
Explanation:
g = Acceleration due to gravity = 
h = Height of reading = 12 cm
= Density of water = 
Pressure due to height difference is given by
The pressure differential is .
