1.A gate having a cross section shown ( no diagram ) closes an opening 5 ft wide and 4 ft high in a water reservoir. its center of gravity is one foot to the left of AC and 2 ft above BC. Determine horizontal reaction developed on the gate at C.
2.A liquid has the peculiar property that its mass density increases linearly with depth according to the expression p = p_water (1+0.01d) where d is the depth below the liquid surface in meters. At a depth of 10 m, what is the gage pressure?
knowing that both members are in compression and that the force is 15 KN in member A and 10 KN in member B, determine by trigonmetry the magnitude and direction of the resultant of the force applied to the bracket by member A and B.
A centrifugal water pump has an impeller with r1 = 4", r2 = 12", f1 = 160°, f2 = 170°. The impeller is 2" wide at the inlet end and ¾" at the outlet. For a speed of 1800 rpm, neglecting losses and vane thickness
calculate the cracking moment (resisting moment) for an unreinforcedconcrete beam that is 10 in. wide, 16 in. high. assume normal weight concrete with 3000 psi = f prime sub c. use the internal couple method and check with the flexure formula.
what is the magnitude and direction of the force of the water n the nozzle, if the nozzle is held steady/2- what is the FORCE if the fire fighter is running towards the fire, with the hose at a velocity of 1.5 m/s
Determine the location e of the shear center, pt. O, for the thin-walled member having the cross section shown. The member segments have the same thickness t.
The bottom of a rectangular flume is 5mabove reference level. The depth of the water in the flume is 3m.The average velocity is 1.7 m/s. Compute the total hydraulic energyat the surface of the water and at the bottom of the flume.
Suppose that all the dislocations in 1000 mm^3 (1 cm^3) were somehow removed and linked together end-to-end. How far (in miles) would this chain extend
Martin pays rent of $500 per month for the 9-month acedemic year, he is going to travel the world this summer and won't be working. how much must he set aside in his savings account for the 3-month summer to cover his rent for the next year
Determine whether a jump may occur at an initial depth of 0.5 m or not. If a hydraulic jump occurs, determine the sequent depth (conjugate depth) to this initial depth
What is the contact time (min) required to achieve a log-3 deactivation of Giardia in water of 10 °C temperature, at pH 7, if the chlorine concentration is 2.2 mg/L
A water contains a suspended solids concentration of 10.30 mg/L.Coagulation reduce this to 1 mg/L.To accomplish this,an alum dose of 13.30 mg/L is necessary.
Draw the flow net for the steady state seepage flow which occurs under this wall. From the flow net determine the distribution of water pressure on the side AB of the wall and then find the resultant force (per metre run into the page) exerted by ..
