GE1301- PROFESSIONAL ETHICS & HUMAN VALUES 2 MARKS QUESTIONS AND ANSWERS

1. What are human values?
Values decide the standard of behavior. Some universally accepted values are freedom
justice and equality. Other principles of values are love, care, honesty, integrity, self
respect.
2. What are ethical values?
Trustworthiness, respect, responsibility, fairness, caring is ethical values
3. Distinguish values from ethics and culture.
Values are mainly related to individuals and since they are related to justice, they remain the
some for every one. E.g. truth, honesty, empathy, self respect.
Values do not change from individual to individual. Ethics is common to a group of
individuals; the group may be religious or professional. Ethics is mostly based on some code
or law and judgment of any action is based on code of conduct or law. Ethics change from
individual to individual
Culture commonly refers to conduct of a group. E.g system of worship, marriage
It may differ from society to society, nation to nation or religion to religion

APPLIED HYDRAULICS AND PNEUMATICS - 2 Mark Q & A for Unit-2 & 3

UNIT - II

1.     What is the function of a pump in a hydraulic system?

                        A pump which is the heart of the hydraulic system converts mechanical energy in to hydraulic energy. The mechanical energy is delivered to the pump via a prime mover such as an electric motor.

2.     What is the function of hydraulic actuator?

                        The fluid discharged by the pump is directed to the hydraulic actuator. The actuator converts the pressure energy of the fluid in to mechanical energy.

3.     A pump has a displacement volume of 98.4 cm^{3 /} rev. It delivers 1.52 litres/sec. at 1000 rpm and 70 bar. If the prime mover input torque is 120 Nm. What is the over all efficiency of the pump? (Ap-May-04)

            The volumetric displacement is,

                  V_D = 98.4 cm^{3 /} rev * (1m / 100 cm) 3 = 0.000100 m^{3 /} rev

            Now we have,

                  Q_T =   V_D . N = (   0.000100 m^{3 /} rev) (1000 / 60 rev/sec) = 0.00167 m³/ sec

            Now the volumetric efficiency is,

                  η_V  = ( Q_A/ Q_T ) * 100 = ((0.00152 m³/ sec) / ( 0.00167)) * 100 = 89.8%

            Now the mechanical efficiency is,

                                                                          (70*10⁵ N/ m²) (0.00167 m³/ sec)

                  η_m = ( P.Q_T / T_A . N) * 100  =       _____________________________ 

                                                                          (120 Nm) (1000 * 2╥ / 60 rad / sec)

                  η_m = (11,690 / 12570) * 100 = 93.0 %

            Therefore the overall efficiency is ,

                  η_o  = (η_{v *} η_m) / 100 =(89.8 * 93) / 100 = 85.5%

4.     What do you mean by cushioning of Fluid power actuators?

                        Due to the inertia force, the piston will hit cylinder head at full speed. To overcome this, cylinder cushioning is provided by which the hydraulic cylinder can be slowly retarded or cushioned.

5.     Define mechanical efficiency.

                        It indicates the amount of energy losses that occur due to the reasons other than leakages. This includes friction in bearings and between other mating parts.

                                    Theoretical Power required for operating the pump

             η_mech  =         ---------------------------------------------------------         * 100

                                    Actual power delivered to the pump
