head loss is 57.61 ft (17.6 m) of water.

TABLE 8 Sample Calculation for Full Flow through Cooling
Circuit* (Fittings and Piping in Circuit)

Compute the head loss for 0, 0.2, 0.4, 0.6, and 0.8 load on the engine,

using the same procedure as in steps 1, 2, and 3 above. Plot on the pump
characteristic curve, Fig. 9, the system head loss for each load. Draw a curve
A through the points obtained, Fig. 9.

Compute the system head loss for condition b with half the jacket water
[150 gal/min (9.5 L/s)] passing through the heat exchanger and half [150
gal/min (9.5 L/s)] through the bypass circuit. Make the same calculation for
