A volume of water at standard conditions is in a cylindrical vertical tube, with a movable piston at the bottom and the top of the tube open to atmosphere. To move the water up the tube, the piston accelerates the water volume at a constant rate. Assuming you know the height of the water in the tube, and assuming you can neglect viscous forces, you need to calculate the pressure on the piston. You should use.

A large water fountain pump floats in water and is held by a rigid horizontal rod as shown in Fig. 3 The pump produces a cylindrical water jet at 609. The jet exhausts to the atmosphere at atmospheric pressure and originates from the pumping device that accelerates the flow from zero velocity inside the pump Volume. The flow rate of the jet is 1 and its diameter is 2/Vĩm. You can ignore frictional losses, the gravitational forces in the jet,...

A piston with a radius of 2.5 cm is placed into a cylindrical tube a distance of 4.5 cm from the closed end of the tube, holding in a quantity of air. The piston is attached to a spring with a spring constant of 324 N/m. The other end of the spring is attached to a rigid wall. The tube is surrounded in ice water which keeps the gas at a temperature of o°C. Initially, the spring is relaxed, and...

Water can be considered as a non-viscous incompressible fluid of density p. A laboratory set-up is such that water flows through a pipe, exhibiting a laminar and steady-state flow. At the top end of the pipe, the flow tube has a cross-sectional area A and point 1 (located on the central streamline) is exposed to the ambient environment. The pipe drops through a A vertical distance h7 while its area decreases to when it reaches point 2 (also on the...

A 0.01 mL spherical air bubble is injected into a polycarbonate cylindrical tube approximately 1.8 m in height and 0.125 m in diameter. The tube is filled up with water. The air bubble rises slowly in water due to the buoyancy force. The drag and gravity forces are also acting on bubble when it rises. After some intervals, bubble achieves the terminal velocity (U,) at steady state conditions where all forces are balanced. The drag force of the water on...
