The narrow tube used as a metering device in refrigeration and air conditioning systems is called a capillary tube. It helps to regulate the flow of refrigerant into the evaporator coil to control the cooling process.
pulse of current is produced at every burst of radiation ending geiger muller tube. when this radiation hits the argon atoms; present in the tube electrons are knocked off.
The pulse point at the knee is called the popliteal pulse. It can be felt behind the knee joint.
it is called the femoral pulse.
What causes the throbbing called a pulse?
Tibial pulse or more technically the Tibialis posterior pulse.
It's called the apical pulse. For future reference: Radial pulse - at your wrist next to your thumb on both arms. Carotid pulse - at your neck. Apical pulse - at your chest. Brachial pulse - anticubital (opposite of the elbow side).
There are several manufacturers good refrigeration that have been in business for decades. One of the leading companies is called True Refrigeration.
The carotid pulse. Its in the neck on either side of the throat.
Capillary tube is a very simple device and can be manufacture easily at low cost. The capillary tube can limit the maximum amount of refrigerant to be charged eliminating the need for a receiver in the refrigeration system. Another advantage is when the refrigeration plant is stopped, the pressure along the capillary tube and the entire system remains constant which means that if the compressor is restarted it does not need moreÊpower to overcome high pressure in the system. Hence, smaller compressors can be used instead of big, expensive ones. A disadvantage with capillary coil is that this system is non adjustable due to the fact that the control of the flow of pressure is dictated by the inside diameter of the tube.
