12.50 An air conditioner operating at steady state takes in moist air at 28°C, 1 bar, and 70% relative humidity. The moist air f

irst passes over a cooling coil in the dehumidifier unit and some water vapor is condensed. The rate of heat transfer between the moist air and the cooling coil is 11 tons. Saturated moist air and condensate streams exit the dehumidifier unit at the same temperature. The moist air then passes through a heating unit, exiting at 24°C, 1 bar, and 40% relative humidity. Neglecting kinetic and potential energy effects, determine a. the temperature of the moist air exiting the dehumidifier unit, in °C. b. the volumetric flow rate of the air entering the air conditioner, in m3/min. c. the rate water is condensed, in kg/min. d. the rate of heat transfer to the air passing through the heating unit, in kW.

A 78-percent efficient 12-hp pump is pumping water from a lake to a nearby pool at a rate of 1.5 ft3/s through a constant-diamet
fenix001 [56]

Answer:

irreversible head loss is 38.51 ft

mechanical power 6.55 hp

Explanation:

Given data:

Pump Power 12 hp = 8948.39 watt = 6600 lbs ft/sec

Q = 1.5 ft^3/s

Pump actually delivers P'  = \eta P = 0.78 \times 8948.39 = 6979.74 watt

Power that water gains= mgh = \rho \phi gh = r \phi h

P = 62.4 \times 1.5 \times 32 = 2995.2 lbs ft/sec

hence Power lost = 6600 - 2995.2  3604.8 lbs ft/sec = 6.55 hp

head losshl = \frac{3604.8}{r \phi} = \frac{3604.8}{62.4 \times 1.5}

hl = 38.51 ft

What is the difference between a cost and a benefit?
goblinko [34]

Answer:

A cost is something you have to give up or sacrifice and a benefit is something that is gained or is helpful.

Explanation:

In a cost-benefit analysis of a system, an engineer is to simply look at the requirements for the system and determine the costs to build the system, both in financial value and energy value.  Additionally, the engineer needs to determine the benefits that would come from choosing a particular path of cost.  If the benefits outweigh the cost for the project, then the solution is accepted.  Else, the cost outweighs the benefit and the solution is rejected.
