Answer:
a. 81 kj/kg
b. 420.625K
c. 101.24kj/kg
Explanation:
t1 = 360
p1 = 0.4mpa
p2 = 1.20
y = 1.13
substitute these values into the equation
when we cross multiply
t2 = 360 * 1.1347
= 408.5
a. the work required in the firs compressor
w=c(t2-t1)
c=1.67x10³
t1 = 360
t2 = 408.5
w = 1670(408.5-360)
= 1670*48.5
= 80995 J
= 81KJ/kg
b.
n = 80%
t2 = 408.5
t1 = 360
0.80 = 408.5-360 ÷ t'2-360
cross multiply to get the value of t'2
0.80(t'2-360) = 48.5
0.80t'2 - 288 = 48.5
0.8t'2 = 48.5+288
0.8t'2 = 336.5
t'2 = 336.5/0.8
= 420.625
this is the temperature at the exit of the first compressor
c. cooling requirement
w = c(t2-t1)
= 1.67x10³(420.625-360)
= 1670*60.625
= 101243.75
= 101.24kj/kg
Answer:
load factor = 0.782
Shrink Factor = 0.833
no of truck is 62500
Explanation:
given data
soil weighs in situ condition = 2,520 lbs/CY
soil weighs in loose condition = 1,970 lb/CY
soil weighs in embanked state = 3,025 lbs/CY
average volume = 16 LCY
soil from a borrow pit = 1 million CCY
solution
first we get here Load Factor that is express as
load factor =
load factor = 0.782
and Shrink Factor will be as
Shrink Factor =
Shrink Factor = 0.833
and
no of truck will be
no of truck =
no of truck is 62500
