If some MWS apparatuses being filled have MDH tank fill intakes and others have LDH tank fill intakes, what is the best hose lay for the fill site operation?

If some MWS apparatuses being filled have MDH tank fill intakes and others have LDH tank fill intakes, what is the best hose lay for the fill site operation?

• A. One LDH and two MDH supply lines.
• B. Three LDH supply lines.
• C. Two LDH and one MDH supply line.
• D. Three MDH supply lines.

Answer: (C)

When filling MWS units that have different tank-fill inlet sizes, you must provide hose lines that match each intake size so every unit can receive adequate flow without forcing incompatible connections. LDH lines carry a larger volume and are needed for the units with LDH tank-fill intakes, while MDH lines fit the MDH inlets and deliver the appropriate flow for those units. The best hose lay in this mixed situation is two LDH supply lines and one MDH supply line. The two LDH lines ensure sufficient flow to the units with LDH tank-fill inlets, helping to minimize pressure loss and keep fill times reasonable. Adding one MDH supply line directly serves the MDH intake unit without using adapters or compromising the fit, ensuring that all three units—two needing LDH and one needing MDH—can be filled efficiently and safely. Using only LDH lines would leave one unit with an MDH intake undersupplied or require awkward adapters. Using only MDH lines would bottleneck the LDH-intake units due to their lower flow capacity. The mix of two LDH and one MDH lines provides the appropriate distribution for mixed intake types and preserves proper connections for each unit.
