SP 2.15. An inverted U-tube manometer containing oil (SG = 2.3) is located
between two reservoirs as shown in the figure below. The reservoir on the
left, which contains carbon tetrachloride, is closed and pressurized to 9 psi.
The reservoir on the right contains water and is open to the atmosphere. With
the given data, determine the depth of water, h, in ft, in the right reservoir.
(Assume the specific weight of carbon tetrachloride is 99.5 lbf/ft3 and the
specific weight of water is 62.4 lbf/ft3.)
SP 2.18. The rigid gate, OAB, shown in the figure below, is hinged at O and rests against
a rigid support at B. What minimum horizontal force, P, is required to hold the gate closed
if its width is 2.0 m? Neglect the weight of the gate and friction in the hinge. The back of
the gate is exposed to the atmosphere.
(Assume the specific weight of water is 9800 N/m3.)
SP 2.19. The gate shown is hinged at H. The gate is 1.6 m wide normal to the plane of the
diagram. Calculate the force required at A to hold the gate closed.
(Assume the density of water is 999 kg/m3 and g = 9.81 m/sec2.)
SP 2.20. The gate AOC shown is 6.3 ft wide and is hinged along O. Neglecting the weight of the gate,
determine the force (in lbf) in bar AB. The gate is sealed at C.
(Assume the density of water is 1.94 slug/ft3 and g = 32.2 ft/sec2.)
SP 2.25 Determine the hydrostatic force vector (in lbf) acting on the radial gate if the gate is 40 ft long
(normal to the page).
(Assume the density of water is 1.94 slug/ft3 and g = 32.2 ft/sec2. The resultant force vector should be
expressed in the following format:
5i -0.25j ------> (5*i)-(0.25*j)
where i and j are unit vectors in the x- and y-directions.)
SP 2.28 Liquid concrete is poured into the form shown (R = 0.348 m). The form is w = 4.9 m wide
normal to the diagram. Compute:
a) the magnitude of the vertical force exerted on the form by the concrete (in kN),
b) the horizontal distance (in m) from the center of curvature of the form to a point along which the
vertical force acts.
(Assume the specific gravity of concrete is 2.5, the density of water is 1000 kg/m3 and g = 9.81 m/sec2.)
SP 2.31 A volume of material (V = 1.06 ft3) weighing 67 lbf is allowed to sink in water as shown. A
circular wooden rod 10 ft long and 3 in2 in cross section is attached to the weight and also to the wall.
If the rod weighs 3 lbf, what will be the angle, , in degrees, for equilibrium?
(Assume the density of water is 1.94 slug/ft3 and g = 32.2 ft/sec2. )

hydraulic fluid is 0.88.)
SP 5.8 Water flows steadily from a tank mounted on a cart as shown in the figure below. After the water jet leaves the nozzle of the tank, it
falls and strikes a vane attached to another cart. The cart's wheels are frictionless, and the fluid is inviscid.
a) Determine the speed of the water leaving the tank (in m/sec), V1,
b) Determine the speed of the water leaving the second cart (in m/sec), V2,
c) Determine the tension in rope A (in N), and
d) Determine the tension in rope B (in N)

SP 5.10 A jet of water issuing from a stationary nozzle at 14.0 m/sec (Aj = 0.07 m2) strikes a turning vane mounted on a cart as shown. The
vane turns the jet through an angle = 60o. Determine the value of M (in kg) required to hold the cart stationary.
(Assume the density of water is 999 kg/m3 and g = 9.81 m/sec2.)
SP 5.17 The nozzle shown discharges a sheet of water through a 180o arc. The water speed is 17.3 m/sec and the jet thickness is 30 mm at a
radial distance of 0.3 m from the centerline of the supply pipe. Find:
a) the volume flow rate of water in the jet sheet (in m3/sec).
b) the y-component of force (in kN) required to hold the nozzle in place.
(Assume the density of water is 999 kg/m3.)
SP 5.21 A steady jet of water is used to propel a small cart along a horizontal track as shown below. Total resistance to motion of the cart
assembly is given by FD = k U2, where k = 0.79 N-sec2/m2. Evaluate the acceleration of the cart (in m/sec2) at the instant when its speed is U =
10 m/sec.
(Assume the density of water is 999 kg/m3.)
SP 5.22 A vane slider assembly moves under the influence of a liquid jet as shown below. The coefficient of kinetic friction for motion of the
slider along the surface is
= 0.37. Calculate:
a) the acceleration of the slider (in m/sec2) at the instant when U = 10.3 m/sec.
