Pool Info: Pool Chloramines. When any type of chlorine is added to water, it forms hypochlorous acid (HOCl - the most powerful killing form of chlorine in water) and hypochlorite ion (OCl-), a relatively weak form of chlorine in water. The percentage of HOCl and OCl- is determined primarily by the pH of the water.
Costa Rica is located between 8 and 12 degrees north of the  Equator. The total distance is 888.17 miles or 1429.36 kilometers.
Distance between San JosÃ©, Costa Rica and the Equator. During our calculation of the distance to the Equator we made three assumptions. 1) We assumed a spherical Earth as a close approximation of the true shape of the Earth (an oblate spheroid). The distance was calculated as great-circle or orthodromic distance on the surface of a sphere.
