Marker Efficiency (Cutting)
Compute the efficiency of a pattern marker in cutting, E = (pieces area / marker area) · 100%, the fraction of the lay actually used by the patterns. The rest is the 'waste' between pieces, an unrecoverable fabric loss — the largest variable cost in garment making. Each percentage point of utilization saves a lot of fabric in scale production. Enter the pieces area and the total marker area.

Marker efficiency (cutting)
Before cutting, the pattern pieces are laid out over the fabric like a jigsaw puzzle — the marker (lay plan). Marker efficiency R = (area of the pieces / marker area) · 100% measures how much of the fabric turns into garment; the rest is the waste between pieces, cloth lost for good. In volume apparel manufacturing this is the largest variable cost: in a plant that cuts thousands of metres a day, gaining 2 percentage points of utilisation saves a fortune in fabric. That is why automatic marker-making software has become standard and why dozens of plies are stacked to be cut in one pass. Good markers run above 85%; below 80%, money is heading straight for the bin. Enter the area of the pieces and the total marker area.

Casting Metal Yield
Calculate the metal yield of a casting process, η = (part mass ÷ total poured mass) × 100%, dividing the finished part mass by the total poured metal (part + risers + runners + spills). The result, in %, measures the metal utilization efficiency: the rest (runners, risers, flash) is remelted, but consumes energy and adds cost. Typical yields range from 50 to 80%, depending on the part and gating complexity. Maximizing yield (well-sized risers, optimized gating) cuts energy and remelting costs. Enter the part mass and the total poured mass.
Elevator Motor Power
Calculate the motor power of an elevator, P = m·g·v ÷ η, from the payload m (kg), gravity g (9.81 m/s²), nominal speed v (m/s) and the system efficiency η (motor, gearbox, sheaves). The result, in watts, is the mechanical power needed to hoist the load at nominal speed. In practice, the counterweight (balancing the car plus ~45% of the load) reduces the effective power, and regenerative braking on descent can return some to the system. It is the base calculation for sizing the traction machine. Enter the load, the speed and the efficiency.

Cheese Yield (Van Slyke Formula)
Estimates how many kilograms of cheese come out of 100 kg of milk using the Van Slyke formula: 93% of the milk fat is added to the casein content, 0.1 point is discounted as loss to the whey, the sum is multiplied by 1.09 to include the salt and ash retained in the curd, and all of it is divided by (1 minus the cheese moisture). The result is the theoretical yield, the reference against which the real plant loss is measured: a gap above half a point between the theoretical figure and the vat balance is almost always fat escaping into the whey or curd cut at the wrong moment. Note that moisture sits in the denominator and dominates the result — the same milk yields 11.2 kg in a soft cheese at 45% moisture and only 9.5 kg in a hard cheese at 35%, and that difference is water, not solids, so a high yield on its own does not mean a better process. The classic Van Slyke form was adopted, with the 0.93 fat retention coefficient and the 1.09 factor; dairies usually recalibrate both numbers for their own process, and for milk standardised by ultrafiltration the formula underestimates the yield. Enter the milk fat, the milk casein and the target cheese moisture.
