Atmospheric air enters an air-conditioning system at 30°C and 70 percent relative humidity with a volume flow rate of 4 m3 /min and is cooled to 20°C and 20 percent relative humidity at a pressure of 1 atm. The system uses refrigerant- 134a as the cooling fluid that enters the cooling section at 350 kPa with a quality of 20 percent and leaves as a saturated vapor. Draw a schematic and show the process on the psychrometric chart. What is the heat transfer from the air to the cooling coils, in kW? If any water is condensed from the air, how much water will be condensed from the atmospheric air per min? Determine the mass flow rate of the refrigerant, in kg/min.
A 45-cm-thick, 300-cm-high lightweight concrete masonry unit wall lies on a 20-cm-thick lightweight plain concrete slab. The 20-cm wide slab is supported by a reinforced concrete beam, which is placed on top of two columns (simply supported beam).
The temperature when the tires were in flated was 25 F. Assuming no change in air mass or volume, what is the temperature (F) in the tire after driving yesterday is a pressure on 44 psig was measured
For cubic crystals, as values of the planar indices h, k, and l increase, does the distance between adjacent and parallel planes (i.e., the interplanar spacing) increase or decrease? Why?
A nearly horizontal, 12 ft wide rectangular channel carries 60 cfs at a depth of 3 ft. the width of the channel is smoothly contracted to 6 ft at the downstream section. (a) determine if the flow will choke and both the downstream and upstream water ..
An uncatalyzed reaction has a rate of 4.2 x 10-7 sec-1. When an enzyme is added the rate is 3.2 x 104 sec-1. Calculate the rate enhancement caused by the enzyme.
Crates A and B weigh 300 lb and 110 lb, respectively. They are connected together with a cable and placed on the inclined plane. If the angle θ is gradually increased, determine when the crates begin to slide.
The segment of river shown has a rectangular cross-section, with width 50 ft. The river bed is at angle ?=100 from horizontal. The average velocity is 2 ft/s at the upstream end (point 1), and 3 ft/s at the downstream end .The vertical depths are as ..
The storage in a reach of river is 20,000 m^3 at a given time. Determine the storage 1 hr later if the average rates of in flow and out flow during the hour are 20 and 18 m^3/s, respectively
Calculate the mass of the green house gas and ozone depleting substance CFC-11 (chemical Formula = CCl3F) in the atmosphere. Use units of GtC (giga tonnes carbon). Production of this substance is now banned and mixing ratios are slowly decreasing wit..
