Page 1 of 4 Expansion Devices I. Introduction Expansion devices are basic components of a refrigeration system which carry out two major purposes: (1) the pressure reduction from the condenser to evaporator pressure and (2) the regulation of refrigerant flow into the evaporator. These expansion devices can be generally classified into two types which are namely the fixed opening type (flow area is fixed) and the variable opening type (flow area changes correspondingly with a change in mass

Slavery has been in the United States early as 1619. Slaves were brought to America for one thing and one thing only‚ money. Tobacco took a great amount of work to harvest‚ but with the slaves help it all got completed. Slaves cost at least three more times than a regular servant for the reason that slavery was their life‚ it was their job. Regular servants finished their ‘slavery’ time in about 4 years. Slavery really got across the whole country as time passed‚ and in 1670 the crop‚ tobacco‚ took

Territorial Expansion was among the great subject of debates during the period 1800-1855. These debates discuss arguments in favor or non-favor of U.S. Expansion. The arguments express concerns‚ fears and advantages the nation will experience by the consequences of expansion. Documents A‚ C‚ D‚ H and I are against territorial expansion.

The Semantics of Slavery and the 13th Amendment In today’s society‚ the idea of slavery is something that happened long ago‚ and it is an idea that today‚ we would consider taboo and most certainly illegal.

Colonists continually tried to allure laborers to the colony. The head right system was to give the indentured servant‚ a method of becoming
