33 1/3
I think it would depend very much on what was recorded on it.
It's 33 1/3 rpm. On any record turntable there should be an rpm switch displaying the speed for 33rpm for LP's and 45rpm for 7 inch singles and if it's a good turntable it should have the speed for an old fashioned 78 rpm record.
33 or 34 I guess.
33 1/3 RPM
there are several speeds for vinyl records, but for common formats it is 33 rpm, 45 rpm, 78 rpm and actually 33 1/3 rpm. that's what they were called 45's because they made 45 revolutions or rounds but it's actually revolutions per minute.
They stopped making 78 RPM records because they became outdated and technology was advancing. After the 78 RPM records of the 1900's, the 33 1/3 RPM records were created.
The 45 RPM record was developed by RCA Victor in 1949 as a competing format for the 33 1/3 RPM (33) format of rival Columbia records that premiered in 1948. Eventually the 45 RPM format (7 inches in diameter with a one-inch center hole) was adopted for shorter recordings while 33 RPM (12 inches in diameter with a 1/4 inch center hole) was used for so called LP (long playing) albums. This eliminated the need to reduce the groove width or quality of 45 RPM recordings.
No, 33 seconds is not particularly old.
33BPH means 33 Brake Horse Power, which is an engine's horsepower measured by a calibrated load placed on the engine. It is often given with an engine speed where the peak power was achieved, denoted as RPM (33 BHP @ 2500 RPM).
