Assuming the same pressure differential (should be about right given little difference in attic temperature/stack effect from changing vents), then the new vent will cause 1% more flow through the attic floor.

3. Roof Vents Remove Warm Air during the Winter. Too many people believe that because heat rises, ventilating an attic space during the winter means you’re releasing warm air and creating a drag on your heating efficiency.
What is a ridge vent?
A ridge vent is an air exhaust vent installed on the peak of a roof. When installing this vent, an air slot is first cut in the roof deck at the roof's peak. This air slot is then covered by the ridge vent itself. They help to provide continuous, uniform exhaust ventilation at the highest portion of the attic and are designed to help resist wind-driven rain and snow, as well as insect and debris infiltration. R idge cap shingles are then typically installed over the ridge vent to protect it, and provide a clean finished look on the roof, with the exception of metal ridge vents which do not require the use of ridge cap shingles.
When are they needed?
Depending on the amount of exhaust ventilation needed for the attic space and the physical roof design, many homes are great candidates for ridge vents. For example, homes that have an ample amount of ridge line are often properly ventilated using ridge vents.
Why is ventilation important in the attic?
A balanced attic ventilation system is important to help prevent roofing system issues. This ventilation system consists of both ridge vents installed at the peak of the roof and intake vents installed at or near the soffits. Properly ventilating your attic helps reduce excess heat and moisture in the summer and also helps keep your roof system cold during the winter to reduce the freeze thaw cycle that creates ice dams.

Why are roof vents good?
Allows Natural Exchange of Air. A great thing about roof ridge vents is that you don’t have to put in extra effort, as the whole air exchange process is quite natural. As the hot air rises, it escapes in the outside environment due to the pressure difference.

Ridge Vent vs. Attic Fan: Major Differences
Roof ridge vents and attic fans both promote airflow in attics. Unlike attic fans, ridge vents are passive, not mechanical, ventilation devices. Also, ridge vents move air both in and out of an attic; attic fans mostly move air outward, from the attic's interior to the outdoors.
Installation
A ridge vent is easier to install when the roof shingles are first installed, but ridge vents can be installed retroactively, too. Roof installers cut through the shingles and the wood roof deck but stop short of the roof rafters, creating a 6-inch continuous slot.
Appearance
Ridge vents blend in well with the roofline. Even with added shingles, ridge vents are barely more than 1 inch high. Since they follow the roof ridge, they are not usually visible.
Cost to Operate
Being passive venting devices, ridge vents are openings in your roof; they do not move. No motors are needed for operation. While ridge vents do occasionally need to be cleared of debris, there is no cost to operate them and little cost to maintain them.
Which Should You Buy?
Attic ventilation of some type is required by most building codes. 1 Ridge vents and attic fans can work in conjunction with each other. In this scenario, the ridge vent passively handles ventilation and cooling duties until it reaches its full capacity. Then, the attic fan takes over.
Why is attic ventilation used?
For example, attic ventilation is used widely even in cold climates to evacuate the warm, moist air that escapes from the living space below. If that air lingers, it can cause condensation on the underside of the roof sheathing – which can lead to wood rot and mold growth.
Why vent your attic?
In warmer climates, proper roof venting helps prevent your attic from becoming a heat trap. Without venting when the sun continuously beats down on your roof, your attic temperature will climb. What most people don’t realize is that heat not only rises, but it also radiates.
Does a soffit vent need an inlet?
While this provides an outlet for air flow, it does not provide an inlet to complete the convection cycle needed for proper ventilation. Soffit vents, when paired with ridge vents, provide complete ventilation for your whole roof surface.
