A rigid tank contains 5kg of water at 20 degrees Celsius. A gage on the tank reads 200kPa. Determine a) the volume of the tank, b) How much would the pressure in the tank increase if the temperature were increased to 50 degrees Celsius. c) A piston reduces (isentropically) the volume of the tank of half its initialvalue. How much id the pressure in the tank expected to increase? ( assume initial temp. 20 degrees)
An empty air tank has a volume of 0.024 m3. The compressor on the tank is run until the pressure gauge reads about 65 psi (or 22,500 Pa). Assuming the temperature of the tank is 25 C, find the density of the air and the weight of the air in the ta..
A 4000-m 3 /day conventional activated sludge plant has an influent with a BOD5 of 190 mg/L and SS of 225 mg/L. What population would this plant serve?
A pump in a large industrial hall containing 30 liters gasoline breaks down, causing the gasoline to spill into a 3 m2 sump surrounding the pump. The liquid pool is ignited by sparks. Assume the combustion to be 70% effective and the heat loss due..
Water flows down a spillway at the rate q = 15 m^3/s into a horizontal channel where v1 = 20 m/s. Determine the depth of flow in the channel y2 that will casue the hydraulic jump to occur in the channel. Determine the headloss hL in the jump.
Compute the maximum acceptable tensile service load T that may act on a single angle L6x4x3/4 that is welded along only one leg to a gusset plate; thus, there are no holes. The service load is three times the dead load. Solve for a0 A36 steel.
Find depth of water flow in Rectangular channel, Water is flowing in a rectangular channel whose width is 5m
The velocity along a pathline is given by V (m/s) = s^2 x t^(1/2) where s is in meters and t is in seconds. The radius of curvature is 0.5 m. Evaluate the acceleration along and normal to the path at s = 2m and t = 0.5 seconds.
A slurry containing 20 percent by weight of limestone (CaCO 3 ) is processes to separate pure dry limestone from water. If feed rate is 2000kg/h, how much CaCO 3 is produced per hour?
A customer randomly select 2 of 10 books to purchase. How many combinations of 2 books can be selected
Determine the heights of the fluid columns for barometers that use the following liquids at 20 C: water, ethyl alcohol, and mercury. Why do you think mercury barometers were used in the past (before the negative health effects of mercury were know..
A rectangular open channel with a width of 10 ft and n = 0.013 conveys a discharge of 300 cfs. The upstream portion of the channel has a slope of 10%, which then abruptly changes to a slope of zero downstream.
for this purpose replace this force by its equivalent of two forces at At Ft parallel and Fn perpendicular to the beam. Determine Ft and Fn.
