Heart rate (HR) is the number of times the heart beats in one minute; normal rates are 60 to 100 beats per minute. Stroke volume (SV) is the amount of blood that the heart pumps out with each beat; the normal amount is 60 to 100 milliliters per beat. A stethoscope is a device that amplifies sounds.hen measuring someone's apical pulse, make sure the patient is rested before trying to count the apical pulse rate. Have the patient lie down and find the apex of the heart. Ask the patient to breathe through his or her nose with normal breaths.
The basic ambient temperature rating point of most motors is 40Â°C. A motor rated for 40Â°C is suitable for installation where the normal surrounding air temperature does not exceed 40Â°C (104Â°F). This is the starting point.
temperature of a pool pump motor Motor A is a non powered reference motor used as a control sample for the ambient temperature as motors will gain heat due to solar radiation This test was done Aug 12, 2013 at Coral Springs FL Ambient Air Temp = 92F Pump was a Hayward Super Pump 1 HP with sp2607 impeller Motors were AO Smith / Century UST-1102 Emerson / US Motor EUST-1102 Ameriblue B1318 (see update) We installed a ball valve in the pump discharge to allow the pump to build 12 psi pressure, as most pools have some friction loss due to filter & piping
