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 Units-those dang Brits) is the amount of heat needed to bring one pound of water to a boil not the size of the grill. However, the bigger the grill, the more BTUs you will have.Gas grills are typically 20,000 - 50,000 BTU. One tip-you should buy your grill based on how often and how much you grill.eport Abuse. The BTU rating is based on the output of the burners. Basically, the more BTUs, the more heat will come out of your burners. For a regular sized BBQ, I would suggest at least 40 000 BTUs.
