A mass acting downward on a piston confines a fluid of density 13600 kg/m2 in a closed container. The combined weight of piston and load on the right is 200 N, and the cross-sectional area of the piston is 8.0 cm2. Find the total pressure at point-B given h= 25 cm.

1. A capillary tube of inside diameter d=6mm connects tank A and open container B as shown in Fig.2. The liquid in A,B and capillary CD is water having a specific weight y=9780 N/m³ and a viscosity of μ=0.0008N s/m². The pressure PA-34.5 kPa gage. Neglecting the minor losses at C and D, determine the flow rate Q through the capillary tube. Assume laminar flow from A to B and use h=32μLV/yd² for the friction loss, where V is the water velocity through the capillary tube.

A patient is receiving saline solution from an intravenous (IV) system. The solution passes through a needle of length 2.1 cm and radius 0.195mm. There is an 8.00 mm-Hg gauge pressure in the patient's vein.Use the density of seawater, 1025 kg/m3, for the solution. Assume its viscosity at 20 °C is 1.002×10−3 Pa·s. a. The actual volume flow rate of the saline solution through the IV system is determined by its passage through the needle. Find the volume flow rate, in cubic centimeters per second, when the saline solution surface is 1.25 m above the patient’s vein.

The small piston of a hydraulic lift (see figure below) has a radius of r1= 1.00 cm, and its large piston has a radius of r2=9.45 cm. What downward force of magnitude F1 must be applied to the small piston for the lift to raise a load of mass 1500 kg? Answer: N.
