Решение. №4 (с. 140)
Решение
А) Конденсационный гигрометр — это прибор, принцип действия которого основан на определении точки росы. Точка росы — это температура, при которой водяной пар в воздухе становится насыщенным. Зная температуру точки росы, можно определить давление водяного пара в воздухе, так как оно равно давлению насыщенного пара при этой температуре. Таким образом, конденсационному гигрометру соответствует физическая величина под номером 2 — давление водяных паров.
Б) Психрометр состоит из двух термометров: сухого и влажного. Испарение влаги с поверхности влажного термометра приводит к его охлаждению, поэтому его показания ниже, чем у сухого. По разности температур между сухим и влажным термометрами с помощью специальных психрометрических таблиц определяют относительную влажность воздуха. Таким образом, психрометру соответствует физическая величина под номером 3 — относительная влажность.
