Air at 1 atm 30 C and 80% relative humidity passes over the cold evaporator coil of an air conditioner at constant pressure. The air and condensate leave the coil at 18C. The moist air flow rate is 0.02 kg/s. using the psychrometric chart determine the following:
i) The dry air mass flow rate (kg/s)
ii) The condensate mass flow rate (kg/h)
iii) The heat transfer from the moist air (kJ/s)
Ferrous metal, nonferrous metal, steel and powdered metals are all examples of:
a simple pulley with the given radius r used to lift heavy objects is positioned 10 feet above ground level. Given that the pulley rotates theta degrees, determine the height to which the pulley is lifted.
a desiccant is being used to remove water vapor from a stream of air with 90 rh at 50oc. the desiccant is a flat plate
a thick steel slab 7800 kgm3 c 480 jkg k k 50 wm k is initially at 300 c and is cooled by water jets impinging on one
the air inside a chamber at 54 c is heated convectively with heat transfer coefficient of 35 wm2k by a 0.29-m thick
the wheel of the slider-crank mechanism shown in the figure is rotating counterclockwise at a constant rate of 10 rads.
Consider a model of a building whose base moves as a result of an earthquake. The building can be modeled as a single-degree-of-freedom spring-mass system where the building mass is lumped on top of two beams used to model the walls of the building. ..
A pin-connected structure consists of a rigid beam ABCD and two supporting bars. Bar (1) is an aluminum alloy [E = 70 GPa] with a cross-sectional area of A1 = 2,400 mm2. Bar (2) is a bronze alloy [E = 100 GPa] with a cross-sectional area of A2 = 6,00..
link bc is 6 mm thick and is made of a steel with a 450-mpa ultimate strength in tension. what should be its width w if
A voltage signal is produced by a transducer. The signal contains its strongest frequency component at 50 Hz (amplitude = 5.0 V), plus a weaker component at the second harmonic (100 Hz) with amplitude 2.0 V. In addition, there is noise at 60 Hz with ..
A piston cylinder contains 0.25 kg of water initially at 1.4 bar and 0.06 m^3. If 250 kj of heat is transferred to the water while keeping pressure constant:
a smaller power plant produces steam at 3 mpa 600 c in the boiler. it keeps the condenser at 45 c by transfer of 10 mw
