Load to be lifted
$$ P_{load} = 10.5 \: t $$ Number of rope falls
$$ n_{falls} = 2 \: $$ Safety factor
$$ s_f = 5.6 \: $$
Minimum required breaking force
$$ F_{breq} = {\left({ P_{load} \cdot g \cdot s_f }\right) \over \left({ n_{falls} \cdot \eta_{reeving} }\right)} \:, kN $$

Pipe length
$$ L_{pipe} = 100 \: m $$ Fluid velosity
$$ V_{fluid} = 3 \: m/s $$ Pipe internal diameter
$$ ID_{pipe} = 0.25 \: m $$ Friction factor
$$ f_{Darcy} = 0.0197 \: $$
Head loss
$$ Hf_{pipe} = {f_{Darcy} \cdot \left({ \left({ L_{pipe} \cdot V_{fluid} ^ 2 }\right) \over \left({ ID_{pipe} \cdot 2 \cdot g }\right) }\right)} \:, m $$
