Hence the relatively small projected sea level rise by the year 2100, as compared to the changes measured in tens of meters that occurred in Earth's history (see Introduction). The rise by 2100 is only a small beginning of a much larger, multi-century response of ocean and ice sheets to elevated global temperatures.
Single Speed Pool Pumps: Runs at a single speed, 3450 rpm (revolutions per minute). Imagine if your car ran at 3450 rpm - all the time, and how much gas you would use! Dual Speed Pool Pumps: Have a fourth wire coming into the pump, the low speed wire. This allows you to run the pump on low speed for 8-16 hrs per day, and high speed for 4-8 hrs. Variable Speed Pool Pumps: Operates at many speeds, programmable and self-optimizing for the highest energy efficiency and greatest energy savings.
Based on the size of your pool (32,000 gallons), for proper filtration in the recommended eight to 10 hours, you will need a pump and filter that can accommodate at least 54-66 GPM. If your filter is actually 48 square feet, the flow rate it can handle should be fine, but each model will vary. dual-speed pump, such as the Pentair SuperFlo Energy Efficient 1-1/2HP Dual Speed Pool Pump â 7.8/3.0A 230V, will allow you to run regular filtration of your 26,000 gallon pool at low speed and increase to high speed for pool cleaning or another feature.
