Operational Amplifier

An operational amplifier also called op amp is an integrated circuit or analog circuit that takes input as a differential voltage and produces output as a single-ended voltage. It is an IC that can amplify weak electric signals.An op amp has one output pin and two input pins. The basic role of an opamp is to amplify the voltage difference between the two input voltages. It is also used in filtering or to perform mathematical operations or in signal conditioning.

Question

Assume that the op amp in the circuit shown is ideal.

In a hydroelectric power plant, water at 20°C is supplied to the turbine at a rate of 0.55 m³/s through a 200-m-long, 0.35-m-diameter cast iron pipe. The elevation difference between the free surface of the reservoir and the turbine discharge is 140 m, and the combined turbine-generator efficiency is 79 percent. Disregarding the minor losses because of the large length-to-diameter ratio, determine the electric power output of this plant. The density and dynamic viscosity of water at 20°C arep= 998 kg/m3 and u= 1.002 x 10-3 kg/m-s. The roughness of the cast iron pipes is ɛ = 0.00026 m. The electric power output of this plant is kW.
