Repeat Prob. 14-83E for a total pressure of 14.4 psia for air.
Prob. 14-83E
Air enters a 1-ft-diameter cooling section at 14.7 psia, 90°F, and 60 percent relative humidity at 600ft/min. The air is cooled by passing it over a cooling coil through which cold water flows. The water experiences a temperature rise of 14°F. The air leaves the cooling section saturated at 70°F. Determine (a) the rate of heat transfer, (b) the mass flow rate of the water, and (c) the exit velocity of the airstream.
A normally consolidated clay soil has angle of friction = 20 degrees and effective stress angle of friction = 28 degrees. If a consolidated undrained test is conducted on this clay
A polystyrene rod consisting of two cylindrical portions AB and BC is restrained at both ends and supports two 6-kip loads as shown. Knowing that E = 0.45 X 106 psi, determine (a) the reactions at A and C, (b) the normal stress in each portion of the..
A fire has destroyed thousands of acres of forest. Seedlings have been planted in the area but are being destroyed by the local wildlife. Develop a way to reforest the region by preventing the wildlife from eating the seedlings
a venturi meter is placed in a pipeline to measure the flow rate of the liquid flowing through that pipe.the meter
water from a treatment plant is pumped into distribution system at a rate of 4.38 m^3/sec, a pressure of 480 kpa and a temperature of 20 degree celcius. The pipe has a diameter of 750 mm and is made of ductile iron
The probability density function, f(t), of the time in hours between storms during the summer in Miami is estimated as f(t) = .014e^(-.014t) if x > 0, f(t) = 0 if x is less than or equal to 0 where t is the time interval between storms in hours.
You are asked to design a pump station to conveywaste water at a flow rate of 250 cubic meters per hour to anequalization tank. A velocity of at least 3ft/s must be maintained in the pipe to prevent deposition and provide scouring of any previously d..
Two simply supported beams are coupled so their centers have equal deflections. The upper beam has length L1 and lower beam has length L2. Determine the deflection of the center of the beams.
If the arm is pulled back such that s= 100 mm and released, determine the speed of the 0.41-kg pinball B just before the plunger strikes the stop, i.e., s= 0. Assume all surfaces of contact to be smooth.
Given the following observations and control station coordinates to accompany Figure, what are the most probable coordinates and error ellipse for station E using a weighted least squares adjustment?
Water at 20ºC flows at a velocity of 2 m/s in a 200-mm diameter horizontal ductile-iron pipe. a) Estimate the friction factor in the pipe, and state whether the pipe is hydraulically smooth or rough.
