Answer:
Distance between manholes = 166.67 (Unit) (Approx)
Explanation:
Given:
Invert elevation = 2605
New Invert elevation = 2610
Grade % = 3% = 0.03
Find:
Distance between manholes
Computation:
Grade % = (Change in elevation)/Distance between objects
0.03 = (2610-2605)/Distance between manholes
0.03 = 5 / Distance between manholes
Distance between manholes = 166.67 (Unit) (Approx)
Answer:
If they can put all these together than what would the difference be between them
Explanation:
Compression ring prevents pressurized refrigerant from blowing past the piston into the crankcase is the false statement.
Answer: Option A
<u>Explanation:</u>
Compression rings seal the combustion chamber from crankcase and then transfer heat to the cylinder from the piston. The piston rings are present in an internal combustion engine or steam engine with multi functions. The functions of piston rings are,
- Ensuring the combustion chamber is tightly sealed as to reduce the loss of gas to crankcase
.
- Promoting heat transfer from the piston to cylinder wall
.
- Controlling engine oil consumption
.
- Optimizing the proper quantity of oil between piston and cylinder wall.
Answer:
a. WATER CONTENT.
mass of water (MW)= 417g - 225g
Mw= 192g
M= (Mw / Ms)
M= [192/417]
M= 0.46
M= 46.0%
b. Void Ration (e)
To calculate the void ratio we must first calculate the volume of solids. Then we can find the volume of voids by subtracting the volume of solids from the total volume.
Ps= (Ms/Vs)=GsPw
Therefore
Vs= (Ms/GsPw)
Vs= (417/ 2.70*1000)
Vs= 0.154cm3
But V= Vv+Vs
Vv=V-Vs
e= (Vv/Vs)
