Answer:
i) 3750 veh/hr/ln
ii) 100 veh/mi/In
iii) 37.5 mph
Explanation:
number of lanes = 3
sf for both directions = 75 mph ( free mean speed )
Dj for both directions = 200 veh/mi/In
<u>Calculate the value of S0, D0 (veh/mi/ln) and maximum Vm (veh/hr)</u>
For either direction we will consider the total volume = 3 lanes
value of Dj = 3 lanes * 200 = 600 veh/mi/
i) value of SO
= ( Dj * sf ) / 4 = ( 600 * 75 ) / 4 = 11250 veh/hr = 3750 veh/hr/lane
ii) Value of DO
DO = Dj / 2 = 200 /2 = 100 veh/mi/In
iii) Value of Vm
= sf /2 = 75 / 2 = 37.5 mph
The condensed Q formula may be used for operations in which the friction loss can be determined for a: 3, 4, or 5 inch hose.
<h3>What is a firehose friction loss?</h3>
A firehose friction loss can be defined as a measure of the effect of the resistance of water against the inner side of a firehose, which typically results in a pressure drop at the terminal end.
Generally, some of the factors that affect the resistance or friction in a firehose include:
Mathematically, the firehose friction loss can be calculated by using this formula:
FL = C × (Q/100)² × L/100.

Hx115 it's pretty fine looking
To resolve this problem we have,
is unknown.
With these dates we can calculate the Flexural strenght of the specimen,
After that, we can calculate the flexural strenght for the square cross section using the previously value.
