7.4 - Hydraulic and Pneumatic Systems

FLUID POWER TECHNOLOGY 7) For the hydraulic system of Figure 3, the following data are given: •The pump is adding 4 kW (pump hydraulic power) to the fluid. •Pump flow is 2000 cm3/s. •The pipe has a 25.4 mm inside diameter. •The specific gravity of the oil is 0.9. Determine the pressure available at the inlet to the hydraulic motor (station 2). The pressure at station 1 in the hydraulic tank is 1 atm. The head loss hL due to friction between stations 1 and 2 is 9.144 m of oil. (Hint: Use Bernoulli’s formula)

### Fluid-Mechanical Circuits   Develop the circuit of a drill in the FluidSim, observing the following requirements:   1.        The design and assembly of the Hydraulic Circuit drive (clamping and working), with the following characteristics:   a.        Sequential operation, put pressure, for the advance and return of the cylinders (according to the proper operation for the device) controlled by a directional 4x3 electric drive way;     2.        The circuit must provide for different speed ranges for drilling work in order to allow different materials to be processed.     Note: Set the safety valve to 55 bar.   *The drill is attached in a figure

Process Dynamic and Control Question

please write clearly if handwritten so that I could read and understand the solutions and steps taken

What would an isometric of the oxygen piping system below look like, where PSA GEN = Pressure Swing Adsorption Oxygen Generator (PSA) COMPs = Compressors POMPs = Pumps HEAT = Heat Exchanger PV = Flow Valves ST TANK = Storage Tank VENT = Vent DR = Drains PSV = Pressure Relief Valve In addition, what would be the possible problems that would require flexibility correction by adding expansion joints, spring supports, anchors and brackets?

PLEASE ANSWER QUESTION # 2 ONLY, DISREGARD THE OTHER PROBLEMS GIVEN. SHOW COMPLETE SOLUTION. THANK YOU.   Intravenous infusions usually are driven by gravity by hanging the fluid bottle at sufficient height to counteract the blood pressure in the vein and to force the fluid into the body (fig. below). The higher the bottle is raised, the higher the flow rate of the fluid will be.   An 8 ft diameter by 16 ft height vertical tank is receiving water (? = 62.5 lb/ft3) at the rate of 295 gal/min and discharging through a 4-in ID line with a constant speed of 6 fps. At a given instant, the tank is half full.     QUESTION #1: the mass change in the tank (sample answer: 20,287.65 lb. round off to 2 decimal place   QUESTION #2: the water level in the tank 15 min. later (sample answer: 20,287.65 ft  round off to 2 decimal place   QUESTION #3: the volume change in the tank (sample answer: 20,287.65 cu ft  round off to 2 decimal place
