INTRODUCTION Open- and closed-loop transfer functions have certain basic characteristics that permit transient and steady-state analyses of the feedback-controlled system. Five factors of prime importance in feedback-control systems are stability‚ the existence and magnitude of the steady-state error‚ controllability‚ observability‚ and parameter sensitivity. The stability characteristic of a linear time-invariant system is determined from the system’s characteristic equation. Routh’s stability

mechanical work from fluid under pressure. One of the famous ways is to use the pressure to accelerate the fluid to a high velocity in a jet. Over the years‚ engineers have found many ways to utilize the force that can be produced by a jet of fluid on a surface diverting the flow. For example‚ the pelton wheel has been used to make flour. Firemen make use of the kinetic energy stored in a jet to deliver water above the level in the nozzle to extinguish fires in tall buildings. Fluid jets are also used

Pull-out and installation of the following: SUBMERSIBLE PUMP [pic] A submersible pump (or electric submersible pump (ESP)) is a device which has a hermetically sealed motor close-coupled to the pump body. The whole assembly is submerged in the fluid to be pumped. The main advantage of this type of pump is that it prevents pump cavitation‚ a problem associated with a

port A at a rate of W kg/s. The steam transfers heat to a fluid at the tube side .The steam condenses during this process and leaves the shell side at the port B at a temperature Ts. The tube side fluid enters the heat exchanger at C with a flow rate of M kg/s at a temperature Ti and leaves at D at a temperature To. The heat loss QH from the steam can be expressed as QH = W(λ + CpH.(Tv-Ts)) Similarly‚ the heat gained by the tube side fluid QC can be expressed as QC= M.CpT. (Ti-To) The heat transfer

Q1 Q1 A) The sudden closure of valve at the end of a pipeline cause sudden change in the water velocity which in turn creates a phenomenon called water hammer. The water in motion is forced to stop or change direction suddenly (momentum change) and a pressure wave propagates in the pipe. It ’s also called hydraulic shock. The effect of this event can be effectively multiplied many times by the geometry of a piping system if the pressure wave is allowed to reflect‚ or bounce‚ back and forth

The Pelton wheel is a water impulse turbine. It was invented by Lester Allan Pelton in the 1870s. The Pelton wheel extracts energy from the impulse of moving water‚ as opposed to its weight like traditional overshot water wheel. Although many variations of impulse turbines existed prior to Pelton ’s design‚ they were less efficient than Pelton ’s design; the water leaving these wheels typically still had high speed‚ and carried away much of the energy. Pelton ’s paddle geometry was designed so that

INTRODUCTION One way of producing mechanical work from fluid under pressure is to use the pressure to accelerate the fluid to a high velocity in a jet. The jet is directed on to the vanes of a turbine wheel‚ which is rotated by the force generated on the vanes due to the momentum change or impulse which takes place as the jet strikes the
