Answer:
The solution for the given problem is done below.
Explanation:
M1 = 2.0
= 0.3636
= 0.5289
= 0.7934
Isentropic Flow Chart: M1 = 2.0 , = 1.8
T1 = (1.8)(288K) = 653.4 K.
In order to choke the flow at the exit (M2=1), the above T0* must be stagnation temperature at the exit.
At the inlet,
T02= = (1.8)(288K) = 518.4 K.
Q= Cp(T02-T01) = = 135.7* J/Kg.
Answer:
The material will not fail
Explanation:
A rod subjected under cyclic stress will fail if the cyclic stress it is subjected to is a constant maximum value that is above the fatigue limit of the rod. but in this problem the Rod is subjected to a cyclic stress that ranges from 200 MPa(maximum stress) and 20 MPa ( minimum stress). this simply means that at all times the Rod will not experience maximum stress of 200 MPa and its Fatigue limit is also set at ~100 MPa
attached is the diagram showing the cyclic stress the rod is subjected to
Answer: speed up food processing
speed up plant growth
Increase fuel efficiency
Explanation:
A catalyst simply refers to a substance that leads to an increase in the reaction rate when it's added to a substance. When the activation energy is reduced by catalysts, this.hwlpa on the speeding up of a reaction.
Therefore,the functions of catalysts include speed up food processing, speeding up plant growth and increase fuel efficiency
Answer:
21.81 %
Explanation:
given,
$600 up to $800 3
800 up to 1,000 7
$1,000 up to $1,200 11
$1,200 up to $1,400 12
$1,400 up to $1,600 40
$1,600 up to $1,800 24
$1,800 up to $2,000 9
$2,000 up to $2,200 4
Total = 3 + 7 + 11 + 12 + 40 + 24 + 9 + 4 = 110
the frequency of $1,600 to $1800
=
=21.81 %
Technician B says that an overfilled gearbox will cause aeration of the lube and cause premature damage this is true.
<h3>How do you lubricate a gearbox?</h3>
Bath lubrication is the only approach for gearbox lubrication. You take any aspect that wishes lubricant and absolutely submerge it in a tub of oil. Bath lubrication is extra typically used for small and medium-sized gearboxes in which the shafts are on a single horizontal axis.
A transmission is a gadget in an electricity transmission system, which gives managed software of the electricity. Often the time period transmission refers genuinely to the gearbox that makes use of gears and equipment trains to offer velocity and torque conversions from a rotating electricity supply to every other device.
