Pressure half time is the time required for the peak pressure gradient to reduce by half (1/2) which will correspond to a decrease in peak velocity by a factor of square root of two (21/2). Pressure half time of a regurgitant jet depends on the severity of the regurgitation and the compliance of the receiving chamber.
Tripping classes of the thermal overload relays Standard classes in IEC 947-4-1 are classes: 10 A, 10, 20, 30. The tripping class indicates according to IEC 947-4-1 the maximum tripping time in seconds under speciï¬ ed conditions of test at 7.2 times the setting current and speciï¬ es tripping and non tripping times for 1.5 and 7.2 times the setting current. Mostly used class is 10 A. Abstract from IEC 947-4-1 Tripping class 10 A 10 20 30 Max. tripping time
