Water is boiled in a pan covered with a poorly fitting lid at a specified location. Heat is supplied to the pan by a 2-kW resistance heater. The amount of water in the pan is observed to decrease by 1.1908 kg in 30 min. If it is estimated that 75 percent of electricity consumed by the heater is transferred to the water as heat, determine the local atmospheric pressure in that location. Use data from the tables.

The local atmospheric pressure in that location is 86.1 kPa.

Explanation:

Using the rate of evaporation and rate of heat transfer the heat of evaporation is calculated as follows.

Now, using enthalpy of vaporization the local atmospheric pressure is determined from data in A-5 using interpolation:

Thus, we can conclude that the local atmospheric pressure in that location is 86.1 kPa.

this is an example of "committed" time.

committed time, as contracted time, takes need over essential and available time since it is seen as profitable work. it alludes to the time allotted to keep up a home and family. at the point when a man is commuting using committed time this individual may feel that the drive is an obligation to family, for example, strolling youngsters to class or driving a mate to work. contracted and committed time clients may feel that their commute could really compare to the commute of important or leisure time clients on the grounds that their commute is profitable work. in this manner, they might be more disposed to pick a mechanized method of movement.
