What is the temperature rise of 250 cfm of air if an electric heater adds 8500 btus to the air?
31.48 deg F
Why should the immersion heater be placed at the bottom of the storage tank?
It gets warm but only if the immersion heater is switched on. The warmer water will rise slowly and start circulating in the tank, so you end up with a tank full of hot water.
Blowing cold air 2001 Montana?
Low coolant? Thermostat not closing allowing engine temperature to rise? Plugged heater core? Air bound heater core? Water pump not circulating coolant?
Is the Btu rating of a pool heater the input Btu of the gas or the transfered Btu going into the water?
input of gas heater The heater has its own BTU rating separate from the gas and the heat transferred. Every heater has an efficiency rating... for instance, a heater can be rated at 92%. This means that for every BTU burn in the heater, 92% of that BTU is transferred in to the water. The main premise behind BTU ratings and pool heating is that most forget the parallel factors involved. How many gallons, and what is the temperature rise? A 200k heater and a 400k heater can both handle, maintain, and work at the same efficiency. The true difference in them is the time it takes to create the rise in temperature. If the pool is 60 degrees, and you want the pool 80 degrees, then you'll need 1 BTU to raise each pound of water 1 degree. The only remaining variable is the quantity of water which will tell you the total weight of the water.
No heat in 1990 Chevy Camaro?
Low coolant? Thermostat not closing allowing engine temperature to rise? Plugged heater core? Air bound heater core? Water pump not circulating coolant? Heater control cable not adjusted properly? Bad selector switch?
How is an electric water heater wired?
Hot water tanksAmps = Watts/Voltage. 4500/240 = 18 amps. You would use a #12 copper wire which is rated at 20 amps. On a hot water tank there is only one of the elements on at a time. The incoming cold water is taken to the bottom of the tank through a pipe inside the tank. When the lower thermostat senses the cold water, the lower element turns on. As you draw hot water from the top of the tank the cooler water from the bottom will rise. When the top thermostat senses the cool water it shuts off the bottom element and turns on the top element. When this water is heated to the tank set point it shuts off and the lower element turns on to heat the rest of the water. When the total tank temperature is at the set point all elements turn off. By using this type of procedure there is always hot water at the top of the tank for use.Actually, not all of this first answer is correct! A 4500 watt heater will draw around 18.75 amps. However, electric water heaters are considered "continuous loads". This means you can't load it's circuit more than 80%. So a 4500 watt heater circuit must be "sized up" to either a 25 amp or 30 amp circuit. This means that #10 copper wire will also be used. Now, a 3800 watt heater will draw around 15.8 amps. In this case, a 20 amp breaker and #12 copper wire can be used. Always check the heater's nameplate to be certain of it's ratings. The calculation used is correct.
Why can't a balloon rise and leaves earth's atmosphere?
For the same reason that a beach ball can rise high in the water but can't leave the water. A balloon is floating in air. If there is no air around it, then it has nothing to float in.
When you put a fish in water will the water rise?
The fish being comprised mainly of water would not cause the water to rise since they are made of the same thing. Actually, the water would be displaced around the fish, forcing the water upwards. In other words, in the space where the fish used to be, there is now water.
Why do air bubbles in water rise?
Bubbles are comprised of gases, which have a lesser density than water. Since they are less dense, they get pushed up to the surface, and they rise, lighter than the liquid around them.
When the anchor is thrown into the water will the water level in the pool drop or rise?
The anchor displaces water and the water level will rise.
What comes first Flood or the rise of the water table?
A flood comes before the rise of the water table. The rise of the water table is a gradual rising of the areas that are actually under water all year round. A flood is a sudden rise in the water level.
Does water heater pilot setting still heat water?
The pilot setting will heat the water a few degrees. A gas water heater will have a thermal rating in BTU of 30,000 to 80,000. The pilot light by itself will have about 1,000 BTU. Operating overnight with no water movement and a well-insulated tank, you will observe a temperature rise but certainly not enough for clothes washing, dishwashers, or showers.
