Question

Chapter 15, Problem 15.1EAA

To determine

The primitive and modern definitions of time. Also, which is more accurate

Expert Solution & Answer

Explanation of Solution

Given Information:

Required information on primitive and modern definitions of time is provided in the question. Also, provided is the required information on which is more accurate.

In the bygone days, time was measured by the following of the shadow of the individual. Even today, in some remote areas this is still practiced. The shadow of the individual changed as the day proceeded with no shadow appearing at noon. In the villages, while working in the fields this was the practice of judging for them to attend their daily chores. The setting of the sun and the arrival of the moon was also an indication for the people to return home along with their livestock. There was no other method for the people in the villages and the upper hill regions to understand the day’s progress. However, this is not the scientific way of calculating the time interval. An example would be for steamers on the seas where this method cannot be practiced.

An improvement on judging the time with reference to the shadow was the pendulum clock and later the quartz clock which provided nearly good timings for day to day activities. However, this accuracy was not sufficient for certain activities like flight, missile launching and space travel etc.

Hence, the timing mechanism had to be more accurate and specific accounting for the location also. To get an accurate time counting, they came up with the atomic clock solution. An atomic clock was based from a particular point and accepted internationally-GMT. The atomic clock timings are used for a missile, space launches etc. This way the time counting mechanism evolved.

Conclusion:

The above-cited way shows how the time counting mechanism evolved over time. Modern definition of time is more accurate as compare to primitive definition of time.

This is an old exam practice question.

As shown in the figure below, moist air at T₁ = 36°C, 1 bar, and 35% relative humidity enters a heat exchanger operating at steady state with a volumetric flow rate of 10 m³/min and is cooled at constant pressure to 22°C. Ignoring kinetic and potential energy effects, determine: (a) the dew point temperature at the inlet, in °C. (b) the mass flow rate of moist air at the exit, in kg/min. (c) the relative humidity at the exit. (d) the rate of heat transfer from the moist air stream, in kW. (AV)1, T1 P₁ = 1 bar 11 = 35% 120 T₂=22°C P2 = 1 bar

Air at T₁-24°C, p₁-1 bar, 50% relative humidity enters an insulated chamber operating at steady state with a mass flow rate of 3 kg/min and mixes with a saturated moist air stream entering at T₂-7°C, p2-1 bar. A single mixed stream exits at T3-17°C, p3-1 bar. Neglect kinetic and potential energy effects Step 1 Your answer is correct. Determine mass flow rate of the moist air entering at state 2, in kg/min. m2 = 2.1 Hint kg/min Using multiple attempts will impact your score. 5% score reduction after attempt 2 Step 2 Determine the relative humidity of the exiting stream. Փ3 = i % Attempts: 1 of 3 used
