Answer:
Modulus of resilience will be ![3216942.308j/m^3](https://tex.z-dn.net/?f=3216942.308j%2Fm%5E3)
Explanation:
We have given yield strength ![\sigma _y=818MPa](https://tex.z-dn.net/?f=%5Csigma%20_y%3D818MPa)
Elastic modulus E = 104 GPa
We have to find the modulus
Modulus of resilience is given by
Modulus of resilience
, here
is yield strength and E is elastic modulus
Modulus of resilience
Answer: The answer is A. The company is trying to transfer intellectual capital to a knowledge management system
Answer:
A) energy loss E = pgQtH
Where p = density in kg/m3
g = gravity acceleration in m/s2
Q = flow rate in m3/s
t = time taken for flow in sec
H = height of flow in m
B) power required to run pump;
P = pgQH

Detailed explanation and calculation is shown in the image below
Answer:FALSE
Explanation: A negative pressure respirator is a respiratory system which is known to have a low air pressure inside the mask when compared to the air pressure on the outside during Inhalation.
Most of the personal protective equipment (PPE) which are in use in various industries are examples of Negative pressure respirator device,any leak or damage done to the device will allow the inflows of harmful and toxic Air into the person's respiratory system. AIR SUPPLY SYSTEMS ARE KNOWN TO SUPPLY FRESH UNCONTAMINATED AIR THROUGH AIR STORED INSIDE COMPRESSED CYLINDERS OR OTHER SOURCES AVAILABLE.
Answer:
The spring is compressed by 0.275 meters.
Explanation:
For equilibrium of the gas and the piston the pressure exerted by the gas on the piston should be equal to the sum of weight of the piston and the force the spring exerts on the piston
Mathematically we can write
![Force_{pressure}=Force_{spring}+Weight_{piston}](https://tex.z-dn.net/?f=Force_%7Bpressure%7D%3DForce_%7Bspring%7D%2BWeight_%7Bpiston%7D)
we know that
![Force_{pressure}=Pressure\times Area=300\times 10^{3}\times \frac{\pi \times 0.1^2}{4}=750\pi Newtons](https://tex.z-dn.net/?f=Force_%7Bpressure%7D%3DPressure%5Ctimes%20Area%3D300%5Ctimes%2010%5E%7B3%7D%5Ctimes%20%5Cfrac%7B%5Cpi%20%5Ctimes%200.1%5E2%7D%7B4%7D%3D750%5Cpi%20Newtons)
![Weight_{piston}=mass\times g=100\times 9.81=981Newtons](https://tex.z-dn.net/?f=Weight_%7Bpiston%7D%3Dmass%5Ctimes%20g%3D100%5Ctimes%209.81%3D981Newtons)
Now the force exerted by an spring compressed by a distance 'x' is given by ![Force_{spring}=k\cdot x=5\times 10^{3}\times x](https://tex.z-dn.net/?f=Force_%7Bspring%7D%3Dk%5Ccdot%20x%3D5%5Ctimes%2010%5E%7B3%7D%5Ctimes%20x)
Using the above quatities in the above relation we get
![5\times 10^{3}\times x+981=750\pi \\\\\therefore x=\frac{750\pi -981}{5\times 10^{3}}=0.275meters](https://tex.z-dn.net/?f=5%5Ctimes%2010%5E%7B3%7D%5Ctimes%20x%2B981%3D750%5Cpi%20%5C%5C%5C%5C%5Ctherefore%20x%3D%5Cfrac%7B750%5Cpi%20-981%7D%7B5%5Ctimes%2010%5E%7B3%7D%7D%3D0.275meters)
