Morphea typically appears on your abdomen, chest or back, but it can affect your face, arms and legs.
There are 27.7 inches of water column (wc) pressure in 1 PSI of pressure. So 7wc is about 1/4 PSI. This is the normal pressure that household natural gas is delivered. The normal delivery on propane (LP), for household use is 11wc or a little more than 1/3 PSI. Both of these pressures are the result of the regulators on the gas line. In the case of natural gas, the meter acts as a measure of volume (so you can get a bill) and as a regulator.
A regulated power supply is an embedded circuit; it converts unregulated AC into a constant DC. With the help of a rectifier it converts AC supply into DC. Its function is to supply a stable voltage, to a circuit or device that must be operated within certain power supply limits. The output from the regulated power supply may be alternating or unidirectional, but is nearly always DC. The type of stabilization used may be restricted to ensuring that the output remains within certain limits under
