Abasket strainer is installed in a 15-cm diameter pipe. Pressuregauges are installed immediately upstream and downstream of thebasket strainer. When water flows at 100 m3/hr, the pressure gaugeimmediately upstream of the basket strainer measures 1 bar.
a. When the basket strainer is clean, the pressure immediatelydownstream measures 0.9 bar. Calculate the local loss coefficientof the clean basket strainer.
b. When the pressure drops across the basket strainer by half(i.e., to 0.5 bar after the strainer)at the 100 m3/hr flow rate, itis removed for cleaning. What is the local loss coefficient of thebasket strainer at this point?
A large steel tower is to be supported by a series of steel wires; it is estimated that the load on each wire will be 19,000N. Determine the minimum required wire diameter assuming a factor of safety 5 and that the yield strength of the steel is 900M..
A microwave oven has a rotating plate for uniform cooking. The plate takes 8 seconds to complete one revolution and is driven by three rollers.
Water at 60 degrees Fahreneit flows at 3 cfs through a 150-ft-long duct of 6 in X 9 in cross section. The pressure at the inlet end is 15 psig, and at the outlet, 20 ft higher than the inlet, it is 4 psig.
A dam project specifies 97% compaction. Lab tests on the soil being used indicate that it has a maximum dry density of 1900 kg/m 3 at an optimum water content of 13.2%.
A rectangular plate 5ft by 4ft is at an angle of 30 degrees with the horizontal, and the 5-ft side is horizontal. Find the magnitude of the force on one side of the plate and the depth of its center of pressure when the top edge is (a) at the wate..
If the state standard downstream is not met, the state has informed town 1 that it must treat its sewage further so the downstream standard is met. Use a mass balance approach to show that the state's request is unfeasible.

Assume to just using coal as an electric energy source. Take efficency as %50 for average power plant.If the carbondioxide level is 400 ppm by volume now, what will be the carbondioxide level 10 years later
A photograph is taken of a transverse wave travelling along a length of rope. At this instant the shape of the wave is described by y = (2 m) sin ((0.8 rad.m-1)x+0.8 rad). The speed of the wave is 2 m/s. Calculate the distance between two successi..
What is the difference in the density and specific weight of air if pressure increases from 1 to 50 atmospheres if temperature is kept at 4 degrees Celsius
one of the wells pumps at a rate of 1240 m3/day. the second well pumps at 850 m3/day.if the aquifer has a transmissivity of 2000 m2/day and a storage coefficient of 4x10^-4, when would the wells start interfering with each other.
Ethylene enters a turbine at 10 bar and 450 K, and exhausts at (atm) and 325 K. For mass flow in = 4.5 kg s^-1, determine the cost C of the turbine. State any assumptions you make. Data: H1 = 761.1 , H2 = 536.9 kg^-1, C/$ = (15,200)(1W1/kW)^0.573
