WebbIn forced convection, air or water is forcibly moved across the body surface (such as in wind or wind-generated water currents) and efficiently removes heat from the body. Convection is a very efficient way of heat transfer because it maintains a steep temperature gradient between the body and surrounding air or water. WebbAn evaporative cooler (also known as evaporative air conditioner, swamp cooler, swamp box, desert cooler and wet air cooler) is a device that cools air through the evaporation of water. Evaporative cooling differs from other air conditioning systems, which use vapor-compression or absorption refrigeration cycles. Evaporative cooling exploits the fact that …

Webb1 aug. 1996 · Abstract. We have measured the vapour pressure of caesium over the temperature range 370 °C to 660 °C using a pressure-controlled heat pipe. The equation log ( p /Pa) = a + b / T + c log ( T /K) + dT + eT2 with the coefficients a = 34,573 234, b = -4979,5799 K, c = -9,323 424 7, d = 4,473 313 2 × 10 -3 K -1 and e = -8,684 092 × 10 -7 K -2 ...
