How to find the phase shift (the horizontal shift) of a couple of trig functions Graphing Sine and Cosine with Phase (Horizontal) Shifts, Example 2. In this video, I graph a trigonometric function by graphing the original and then applying the phase shift.
Take the electric hot-water heater recovery times and divide them in half to get the recovery time for a gas unit. Water coming into a 50-gallon tank at 40 degrees takes just 53 1/2 minutes to reach 120 degrees. For 60-degree water entering the tank, calculate about 40 minutes needed for the water to reach the 120-degree temperature. For 70-degree water, it would take 33 minutes.
Electric Water heater problems, I added info.. Two days ago we stopped getting hot water, today we replaced the heating element, we are not however sure if it fixed the problem... how long does it take the water to start getting hot again? Last edited by Devoncroix; 12-20-04 at 03:33 PM.
