Answer
TL/TH- TL
Because we know that power coefficient is. = QL/QH-QL
=so using this for performance we have
=>Perf= TL/(TH-TL)
The correct answer is An abrasive wheel.
Answer:
1. Buy Quiet – select and purchase low-noise tools and machinery
2. Maintain tools and equipment routinely (such 3. as lubricate gears)
3. Reduce vibration where possible
4. Isolate the noise source in an insulated room or enclosure
5. Place a barrier between the noise source and the employee
6. Isolate the employee from the source in a room or booth (such as sound wall or window

Answer:
a) 2622.903 N/m^3
b) 1.38233
c)4.878811765
Explanation:
Find the void ratio using the formula:

Here;
is specific gravity of soil solids
is unit weight of water = 998 kg/m^3
is the moisture content = 0.17
is the void ratio
is the unit weight of soil = 14.9KN/m^3
Saturation Ratio Formula:

S is saturation rate
Substitute Eq 2 into Eq 1


Specific gravity of soil solids

Saturated Unit Weight

Answer:
Electroosmotic velocity will be equal to 
Explanation:
We have given applied voltage v = 100 volt
Length of capillary L = 5 mm = 0.005 m
Zeta potential of the capillary surface 
Dielectric constant of glass is between 5 to 10 here we are taking dielectric constant as 
Viscosity of glass is 
Electroosmotic velocity is given as 

So Electroosmotic velocity will be equal to
