Lithotripsy is a procedure that uses shock waves to break up stones in the kidney, bladder, or ureter (tube that carries urine from your kidneys to your bladder). After the procedure, the tiny pieces of stones pass out of your body in your urine.
Propane gas is ideal for grills because, when pressurized, it compresses and turns to liquid, making it easy to store in tanks. It also contains more cooking energy than natural gas as measured in British Thermal Units (BTU). A BTU is the amount of energy required to raise the temperature of one pound of water 1Â°F. There are about 2,500 BTU in one cubic foot of propane and only about 1,000 BTU in one cubic foot of natural gas. Manufacturers tout the number of BTU their grills can produce, but the number can be very misleading. BTU is not indicative of the heat it can generate.
BTU (British Thermal Unit) is the traditional unit of energy. The heat value of fuels and the heating power of gas grills can be expressed in terms of BTU. It can be defined as the amount of heat energy needed to raise the temperature of one pound of water by one degree Fahrenheit at a constant pressure of 1 atmosphere.ow many BTU do you need? The rule was once 100 Btu per square inch of main cooking area. This rule no longer applies because modern gas grills are now becoming more and more efficient at holding heat. One thing you should know is that the temperature a gas grill can attain is not influence by the BTU rating alone.
