Answer:
V = 0.002524m³/kg
%Error = 0.2851
Explanation:
Using the ideal gas equation, we can determine the specific volume of nitrogen as
PV = RT
V = RT/P
Given the following data:
R = 296.8j/kg.k
T = 139k
P = 8.5Mpa
Therefore, V = (296.8j/kg.k)×(139k)/8500000
V = 0.004853m³/kg
Using the compressibility chart, we can see that the compressibility factor of Nitrogen at this state is equal to 0.52. Using this, we can find out the specific volume of nitrogen to be
Z = PV/RT
0.52 = (8500000Pa)V/(296.8J/kg⋅K)(139K)
V = 0.52×296.87×139/8500000
V = 0.002524m³/kg
%Error = V(ideal)-V(actual)/V(actual)
%Error = 0.002524-0.002002/0.002002
%Error = 0.2609
Error for this compared with the actual value is
%Error = V(ideal)-V(actual)/V(actual)
%Error = (0.004853-0.002002)/0.004853
%Error = 0.2851
Answer:
the answer is the "income tax"
Answer:
850.8480103 feet
Explanation:
First you take the diameter and find the circumference, which is (2)(pi)(r) plug in your r which is 26/2= 13 so 2(13)(pi) and multiply taht by 125 after that take your answer and divide by 12which is 850.8480103
Answer: At time 18.33 seconds it will have moved 500 meters.
Explanation:
Since the acceleration of the car is a linear function of time it can be written as a function of time as
Integrating both sides we get
Now since car starts from rest thus at time t = 0 ; v=0 thus c=0
again integrating with respect to time we get
Now let us assume that car starts from origin thus D=0
thus in the first 15 seconds it covers a distance of
Thus the remaining 125 meters will be covered with a constant speed of
in time equalling
Thus the total time it requires equals 15+3.33 seconds
t=18.33 seconds
