Problem 1. A restrictor is required to flow 0.1 GPM of 50/50 ethylene glycol/water blend (specific gravity = 1.07) at 45°F and 6 psid. How many Lohms are required?
Problem 2. What pressure drop will result from a flow of 57 mL/min. of 50/50 ethylene glycol/water mixture (specific gravity = 1.07) at 45°F, flowing through a 1000 Lohm restrictor?
Problem 3. What restriction will permit a flow of 1 gallon of water per hour at 50 psi ΔP?
Problem 4. A jet with a hole diameter of .012" flows 18 lb/hr of water at 100 psi ΔP. How many Lohms?
Problem 5. What ΔP will be required to flow 20 GPH of water through a 2000 Lohm Jet?
Problem 6. What water flow will result from a restriction of 500 Lohms and a ΔP of 500 psi?
Note: For special flow requirements, The Lee Company can determine the required Lohm rating.
Problem 7. A restrictor is required to flow 0.15 GPM of MIL-H-83282 hydraulic fluid at 80°F and 100 psi ΔP. What restriction is required?
Problem 8. What pressure drop will result from a flow of 5 PPH of SAE #10 lubricating oil at 20°F, flowing through a 1000 Lohm restrictor?
Problem 9. A Safety Screen is required to flow 775 lb/hr of JP4 @ 80°F with a maximum pressure drop of 5 psid. What is the maximum Lohm rate allowed for the Safety Screen?
