Answer:
Explanation:
,K=1.35
Clearance is 8%.
Heat added=15 KJ
We know that compression ratio
r=13.5
We know that efficiency of otto cycle
W is the work out put and Q is the heat addition.
W=8.4 KJ
We know that Work =Mean effective pressure x swept volume.
Here swept volume
Noe by putting the values
Work =Mean effective pressure x swept volume.
Answer:
Explanation:
given data
Load P = 35 kN
Width of bar W = 50.8 mm
Breadth of bar B = 25 mm
Ratio of crack length to width α = a/W = 0.2
solution
we get here KI for a rectangular bar that is express as
................................1
here Y is the geometrical function
so
Y =
Y =
Y =
Y = 0.9878
so put here value in equation 1
= 5210.45 × 10³
= 5.21 MPa
Answer:
The answer is 11.7 ft
Explanation:
You can use the combined gas law from Boyle's law, Charles's law, and Gay-Lussac's Law. Only because hydrogen behaves like an ideal gas for this conditions.
where the subscripts denote the pressure "p", volume "V" and the temperature "T" (in Kelvin) at two different times. Let's consider as the balloom at 150,000 ft so
and .
Then, is the moment when the balloon is on the ground.
and .
From the first equation,
, then
and the radius would be
.
Answer:
Explained below
Explanation:
Beats are interference pattern between two sounds of slightly different frequencies perceived as periodic vibration in volume whose rate is difference of the two.
Both octave and decibel are the terms of measurement.
Octave(In electronics) is a logarithmic unit for ratio between frequencies,with one octave corresponding to doubling of frequency. For example frequency one octave is from 40 Hz to 80 Hz.
Whereas decibel is a unit of sound intensity. It is one-tenth of A bel. In electronics it is used measure power level of an electrical signal by comparing it with given level of logarithmic scale.
