HYDRAULIC TURBINES Meaning of the term ‘Hydraulic’ • The working fluid is a liquid or a gas?? ANSWER – WORKING FLUID IS A LIQUID. TURBINE – WORKING PRINCIPLE • In turbines the pressure energy is converted into mechanical energy(which is further converted into electrical energy). WORKING PRINCIPLE OF PUMPS it is just the reverse of the above‚ that is‚ the mechanical energy is converted into pressure energy. OUR FOCUS OF STUDY • Working of various types of hydraulic turbines.

CHAPTER 7 FLEXIBLE BUDGETS‚ DIRECT-COST VARIANCES‚ AND MANAGEMENT CONTROL 7-1 Management by exception is the practice of concentrating on areas not operating as expected and giving less attention to areas operating as expected. Variance analysis helps managers identify areas not operating as expected. The larger the variance‚ the more likely an area is not operating as expected. 2. Two sources of information about budgeted amounts are (a) past amounts and (b) detailed engineering studies

this statement with relation to the concepts of effectiveness and efficiency and any interrelationships that may exist. Introduction Equity of access‚ as stated in National Health Reform Agreement‚ is one of the fundamental bases of the Australian Health care system (DHA 2013a). Other elementary aspects of the Australian health care system also cover effectiveness‚ which focuses on ratio of outputs to outcomes‚ and efficiency‚ which is defined as achieving maximum outputs with available inputs

ELECTRONICALLY COMMUTATED MOTOR (ECM): (Venkatesan K R‚ Underwriters Laboratories) The ECM (Electronically Commutated Motor) is a high efficiency programmable brushless (no commutator and brush) DC motor utilizing a permanent magnet rotor (loss approximately zero) and a built- in inverter. Brushed DC motor is having lower efficiency and susceptibility of the commutator assembly to mechanical wear and consequent need for servicing. ECM motors can directly replace the existing Brushed DC motors and
