i.      The maximum velocity of the piston and the maximum force that can be applied in the forward stroke.       (2 points)

ii.      The maximum velocity of the piston and the maximum force that can be applied in the reverse stroke.         (2 points)

Hints:

Velocity:           V = Q/A

    V = Velocity of Piston

    A = Area of cylinder cross section,

    Q = volumetric flow rate,

Applied Force, F = p A

    F = Applied force

    p = fluid pressure

    A = Area of cylinder cross section, m2 (in2)

A linear actuator such as you used in lab has a rod of area of 10-4 m2 and a piston area of 3*10-4 m2 . The actuator can have fluid applied to either the piston end of the cylinder or the open end where the rod comes out so the rod can both extend and retract out of the cylinder. A student establishes equilibrium between the hydraulic force and an external weight so there is no movement of the weight....

A piston-cylinder apparatus contains 4 kg of saturated liquid water at 35˚C. The piston’s cross sectional area is 0.06 m2 , and initially it is resting on stops, enclosing a volume of 0.03 m3 . To raise the piston, a pressure of 300kPa has to be applied. Heat is transferred until the volume is 0.075 m3 , at which point the piston encounters a linear spring. To deflect the spring 1 m, a force of 360 kN is required. More...

When gas expands in a cylinder with radius r, the pressure P at any given time is a function of the volume V: P = P(V). The force exerted by the gas on the piston (see the figure) is the product of the pressure and the area: F = πr2P. The work done by the gas when the volume expands from volume V1 to volume V2 is W = V2 P dV V1 . In a steam engine the pressure...

1) A nozzle is a device for increasing the velocity of a steadily flowing stream of fluid. At the inlet to a certain nozzle the enthalpy of the fluid is 3025 kJ/kg and the velocity is 60 m/s. At the exit from the nozzle the enthalpy is 2790 kJ/kg. The nozzle is horizontal and there is negligible heat loss from it. (i) Find the velocity at the nozzle exit. (ii) If the inlet area is 0.1 m2 and specific volume...

3.) What is the most accurate statement concerning the spring constant (k)?          A. The spring constant is the ratio of the displacement of the spring from its equilibrium position divided by the force applied to the spring          B. When the displacement of the spring from its equilibrium position is plotted (y-axis) against the force applied to the spring that caused             C. Spring constant is a unitless number related to the “stiffness” or strength of the spring.            ...

± The Nernst Equation and pH Sulfuric acid is a very strong acid that can act as an oxidizing agent at high concentrations (very low pH, or even negative pH values). Under standard conditions, sulfuric acid has a low reduction potential, SO42−(aq)+4H+(aq)+2e−⇌SO2(g)+2H2O(l),   +0.20 V which means it cannot oxidize any of the halides F2, Cl2, Br2, or I2. If the H+ ion concentration is increased, however, the driving force for the sulfuric acid reduction is also increased according to Le Châtelier's...
