What is the delta P if the gauge at the motor inlet is 380 kPa and the gauge at the motor outlet is 35 kPa?

Explanation:
Delta P is the pressure difference across the motor, found by subtracting the outlet pressure from the inlet pressure. With 380 kPa at the inlet and 35 kPa at the outlet, the drop is 380 − 35 = 345 kPa. The other numbers represent either the individual pressures (380 kPa or 35 kPa) or an incorrect unit conversion (3450 Pa = 3.45 kPa, not the difference).
