Answer:

Explanation:
Let's write the equation of the production rate for the assembly machine :

Where
is the production rate for the assembly machine.
Where
is the ideal cycle time
Where n is the number of stations.
Where m is the number stations that get jam when the defect occurs.
Where p is the defect rate at each station.
And where
is the average downtime per breakdown
We are looking for the hourly production rate ⇒
⇒
⇒

⇒


m = 1.0 in the equation.
Answer:
porosity=23.07%
x=5.974*10^9cm^3
Explanation:
One liter of oven-dry soil sampled from the Chorro Creek Ranch field requires 300 g of water to completely saturate it.
Calculate (a) its porosity, n, and (b) the volume of water required to saturate the top 20 cm of 1 hectare of the field.
-Porosity of a soil sample can be calculated in five ways but i shall use the formula below
porosity=
%
volume pore volume of sample is equal to water volume used to saturate the soil
total volume=sample volume +pore volume
1L=1000cm^3
density of water=density=mass/volume
1g/cm^3=300g/volume
vol=300cm^3
total volume=300+1000
1300
porosity =(300/1300)*100%
porosity=23.07%
2. Recall that volume=area *height
1 hectare=1*10^9cm^2
the volume of soil sample=1*10^9cm^2*20cm
2*10^10cm^3
%
23%=x/(x+2*10^10)*100%
x=5.974*10^9cm^3
Answer:
There are 6 types of pressure control valves and their function is to regulate the pressure below a threshold level within safe limits and to maintain and control pressure of a particular circuit.
Explanation:
The six type of Pressure valve with their functions are given below:
a. Unloading Valve:
These type of pressure valve are used to pour fluid into the container at very low or no pressure.
b. Safety valve:
These are used when the pressure within the vessel is in excess as inside temperature is near about preset [point point then these valves are open to release the extra pressure and are closed once normal conditions are regained.
c. Pressure Reducing Valve:
These are basically used for the control of the pressure in downstream not exceeding the design limits.
d. Pressure Relief Valves:
These are basically used to limit and regulate the pressure of any system.
e. Counter Balance Valve:
These are used to develop pressure in the reverse direction at the actuator's return line in order to keep the load under control.
f. Sequence Valve:
These are used to maintain sequence or order in the operations of two parts or branches.
