Water in an open dish exposed to dry air at 25oC is found to vaporize at a constant rate of 0.04 g/h-cm2. Assuming the water surface to be at the wet-bulb temperature of ll.0Â°C, calculate the effective gas-film thickness (i.e., the thickness of a stagnant air film that would offer the same resistance to vapor diffusion as is actually encountered at the water surface). ....

For the following problems, sketch a schematic wiring diagram showing the connection of the ungrounded, grounded, and equipment grounding conductors to the wiring devices. Where switching is specified, designate the contact switching arrangement for each device (SPST, DPST, ect).1. two lighting outlets controlled by two switches. The tow bulbs must be in parallel, please include two SPDT switches, phase, neutral and grounding conductors.2. a duplex receptacle with one receptacle outlet always .... Read More

A suction device is being designed based on the venturi principle to lift objects submerged in water. Theoperating water temperature is 15Â°C. The suction cup is located 1 m below the water surface, and theventuri throat is located 1 m above the water. The atmospheric pressure is 100 kPa. The ratio of the throatarea to the exit area is , and the exit area is 0.001 m2. The area of the suction cup is 0.1 m2.a. Find the velocity of the water at the exit for maximum lift condition.b. Find the .... Read More

Two aqueous sulfuric acid solutions containing 20.0 wt% H2SO4 (specific gravity = 1.139) and 60.0 wt% H2SO4 (specific gravity = 1.498) are mixed to form a 4.00 gmol/L H2SO4 solution (specific gravity = 1.213). What feed rate of the 60% solution (L/h) would be required to produce 1250 kg/h of the product .... Read More

A 30 ft tape weighing 3 lb and with a cross sectional area of 0.01 in2was standardized and found to be 30.02 ft at 680F, with 20 lb tension and fully supported . This tape was used to measure a total distance of about 80 ft. The first 60 ft has a uniform 30% slope but the other 20 m was horizontal. The temperature was constant at 850F, the tape was fully supported throughout and a tension of 30 lb was applied to each tape length. The observed distances were 30.0 ft, 30.0 ft., and 20.0 ft. ....
