thi 40 A vertical sluice gate (4m) wide and (3m) deep contains water on both of its sides. On the upstream side, the water is (6m) deep and on the downstream side it is (2.5m) deep from the bottom of the sluice. What is the resultant pressure force on the gate and the position of this resultant force from the hinge
Suppose a u-bend is redirecting a flow of water. The water enters flowing to the right at 10 m/s. The u-bend completely reverses the direction of the flow, so the water leaves flowing to the left. The area of the u-bend is constant, a circular cross-section of 0.12 m. The pressure in the fluid is measured at 50 kPa. The length of the u-bend is 0.46 m. Find the force, including magnitude and direction, to hold the u-bend in place.
A 30 cm diameter pipe carries water under a head of 15 metres with a velocity of 4 m/s. If the axis of the pipe turns through 45°, find the magnitude and direction of the resultant force at the bend.
A rectangular plate of weight 6 kg is suspended vertically by a hinge on the top horizontal edge .The cg of the plate is 10cm from the hinge. A horizontal jet of water 2cm diameter ,whose axis is 15 m below the hinge, impinges normally on the plate with a velocity of 5m/Sec . Find the horizontal force applied at the cg to maintain the plate in its vertical position. find the corresponding velocity of the jet if the plate is deflected through 30 degree and the same for continues to act at the cg of the plate
A water flows through a 2-in opening in the side of a tank. If the opening is 8 ft below the surface of the water, what volume of water would escape from the tank per minute?
For a centrifugal pump of impeller diameter D rotating at N to develop a head of H and discharge Q, what would be the new head developed by a similar pump if we double the impeller diameter to 2D at constant impeller speed?
Let's consider a snowplow which is scooping up snow 2 cm deep (d) and the blade is 1 m wide. Lets assume the specific gravity (SG) of snow is 0.2. If we want to plow at 55 km/hr and a 30 degree vertical angle of discharge: (a) what is the force exerted on the blade? (just treat the snow like a fluid of density 200 kg/m^3). (b) what is the power necessary? (c) Suppose with the 30 degree vertical angle of discharge would this change the force exerted on the blade? what would it be if it changes? (It might occur to you that it does little good if we don't angle the blade as we just throw the snow in front of the truck...still in the roadway..)
Pumps: A centrifugal pump having 4 stages in parallel, delivers 18 kiloliters/min of liquid against a head of 25 m. The diameter of the impellers being 24 cm and the speed of 1800 rpm. A pump is to be made up with a number of stages in series of similar construction to that of the first pump to run at 1250 rpm and to deliver 15 kiloliters/min against a totalhead of 250 m. Find the diameter of the impellers and the number of stages required in this case. Answer: D = 46.63 cm, n = 6 stages
For a tank, calculate the volumetric flow of water, which comes out through a pipe, the tank is sealed, the depth is h1=2M, Qexit=0.05,substance water Vexit=? and Q=?.
You only know one point on a pump curve, where a water pump produces 20 m of hydraulic head at flow rate of 3.67 L/s, and you want to use this to pump water from a lower tank to an upper tank located 15 m higher. Both tanks are open to the atmosphere. Briefly explain your reasoning, in 1‐2 sentences, for each of the following. a) Should this pump be placed next to the lower tank or the higher one? b) Given the data point you have from the pump curve, will the flow rate be higher or lower than 3.67 L/s if the water is pumped exactly 15 m uphill?

A fire hose nozzle has a diameter of According to some fire codes, the nozzle must be capable of delivering at least 250 gal/min. If the nozzle is attached to a 3-in.-diameter hose, what pressure must be maintained just upstream of the nozzle to deliver this flowrate?
