Minor Losses examples, formula and calculator
I want to calculate 

Velocity (V)  
Closed Conduits Energy Loss Coefficient (K)  
Head Loss (HL)  
Examples Of Head Loss (H_{L}):
Example 1:
Velocity (V) = 3,
gravity = 9.8,
Closed Conduits Energy Loss Coefficient (K) = 5,
find Head Loss (H_{L}) = ?
Sol :
Velocity (V) = (3*3)
Formula Values = 9/(2*9.8)
Head Loss (H_{L}) = 5 * 0.459 => 2.295
Example 2:
Velocity (V) = 6,
gravity = 9.8,
Closed Conduits Energy Loss Coefficient (K) = 10,
find Head Loss (H_{L}) = ?
Sol :
Velocity (V) = (6*6)
Formula Values =36/(2*9.8)
Head Loss (H_{L}) = 10 * 1.83673 => 18.367
Example Of Velocity (v):
Example 1:
Head Loss (H_{L}) = 5;
Closed Conduits Energy Loss Coefficient (K) = 2.5,
gravity = 9.8,
find Velocity (V) = ?
Sol:
Formula Values = 2*9.8*5 = 98
Result = 98 /2.5 = 39.2
Velocity (V) = √ (39.2) => 6.2609
Example 2:
Head Loss (H_{L}) = 15;
Closed Conduits Energy Loss Coefficient (K) = 5,
gravity = 9.8,
find Velocity (V) = ?
Sol:
Formula Values = 2*9.8*15 = 294
Result = 294 /5 = 58.8
Velocity (V) = √ (58.8) => 7.668
Example Of Closed Conduits Energy Loss Coefficient (K) :
Example 1:
Velocity (V) = 5,
Head Loss (H_{L}) = 7 ,
find Closed Conduits Energy Loss Coefficient (K) = ?
Sol :
Formula Values = (2*9.8)/(5*5) = 0.784
Closed Conduits Energy Loss Coefficient (K) = 7*0.784 => 5.488
Example 2:
Velocity (V) = 7,
Head Loss (H_{L}) = 9 ,
find Closed Conduits Energy Loss Coefficient (K) = ?
Sol :
Formula Values =(2*9.8)/(7*7) = 0.4
Closed Conduits Energy Loss Coefficient (K) = 9*0.4 => 3.6
