7.4 - Hydraulic and Pneumatic Systems

Noun Explanation (a)Pressure Control Circuits (b)Hydraulic System of Manipulators (c)The Approach for Design of Hydraulic System

A certain hydraulic system is designed to exert a force 100 times as large as the one put into it. (a) What must be the ratio of the area of the cylinder that is being controlled to the area of the master cylinder? (b) What must be the ratio of their diameters? (c) By what factor is the distance through which the output force moves reduced relative to the distance through which the input force moves? Assume no losses due to friction.

please help solve for part A)   Q3 part a, for this system the changes in internal, potential and kinetic energies are all ≈ 0, so that  .  This seems odd, but the water is merely transferring work from the pump to the piston, rack and car.  Here the   W s the algebraic sum of the work done on the water by the pump and the work done by the water on the piston, rack and car ( i think)

Explain the working principle and applications of a centrifugal pump in the context of mechanical engineering.

1. A downward force of 100 N is applied to the small piston with a diameter of 50 cm in the hydraulic lift system shown below.a. What is the upward force exerted by the large piston with a diameter of 2m?b. What is the mechanical advantage of this hydraulic lift?c. If the input force of 100N pushes the small piston down by 2m, how high will the large piston rise? 2. Water flows through a circular pipe with a constant radius of 10cm. The speed and pressure at point A is 4m/s and 250,000Pa respectively.a. What is the speed of the fluid at Point B? b. What is the pressure at point B which is 10m higher than point A?

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

A pump has a displacement volume of 6 in^3. It delivers 24 gpm at 1000 rpm and 1000 psi. If the prime mover input torque is 1100 in • lb, what is the theoretical torque required to operate the pump in in-lbs?

Suppose that you have designed a portable compressed-air supply system, as shown in the figure below,for filling scuba tanks and for driving pneumatics tools in garages and factories.The system consists of an electric motor, an air compressor, an air tank, a regulator and a pressure-reliefsafety valve.The regulator contains a pressure sensor connected to a power switch. The motor is switched on whenthe tank pressure drops bellow a fixed value and off at a slightly higher pressure. The pressure-reliefvalve is set to open at a higher pressure than the regulator motor off-pressure.Explosion of the tank is clearly a dangerous hazard. Three events are assumed to possibly lead to a tankexplosion:1. an internal tank defect such as poor welding2. an external cause such as a plant vehicle colliding with the tank3. Excess pressure in the tank. The excess pressure can occur only if both the control unit and thepressure-relief valve fail:The pressure sensor might fail to shut oof the motor because…

what is the best type of pump for use in a hydraulic system, and which would be the best for a pneumatic system. Explain your reasoning.

A Large wind turbine has blade span diameters of 110 m. It sits high off the ground where the average wind speed is 7 m/s. Assume the air density to be 1.25 kg/m3, and the efficiency of the wind turbine, its generator and its electric grid synchronization device is 26%. What is the average electric power that this turbine can output to the grid? a. Sketch the problem. b.Draw lines identifying the control volume, or control mass. c.Identify the states with numbers, letters, or descriptions such as “in” and “out”. d.Write down the knowns and unknowns. e.Identify what is being asked for. f.State all assumptions.

State 5 main faults and hazards in the pressurized system andthe way to avoid them. Also, state the different steps withpictures if possible the way the vane pump can be repaired. Thencompare the different safety issues between pneumatic and hydraulicas there are differences in the pressure. Finally, use thefault-finding technique to show how to solve the lack of pressureto the cylinder for a pneumatic circuit and the importance of maintenance to avoid these problems in the future.

Write the working of hvac and its components for high rise multi-resedential bulding. Identify the below pictures and explain their role.

2. A centrifugal pump installation draws water from an underground well whose free surface is 50 m below ground level. Water is pump to a reservoir 6 m above ground. Suction pipe diameter is 150 mm and the discharge pipe diameter is 100 mm. The required capacity of the pump is 250 liter/sec. If the pump efficiency is 82%, determine the required brake power for the motor drive. a. brake power Answer : _______________ kW
