Normal water pressure readings for 2004 F150

[horsetrader]

What are the expected normal water pressure readings for a 2004 F150 at various rpms? The water pressure gauge shows little or no pressure at idle (as would be expected) but a higher rpms (3000-4000), the gauge only reads 10psi but cooling water from the pilot tube is strong and water temp is normal. Should normal operating pressure be higher or is it in the ballpark as is?

Thank You in advance,

The mininum is 10 psi at wide open throttle.
