Using MATLAB Simulink, set up the negative feedback system of and find the value of the gain
a) Plot the step response of the system at each value of t to yield over damped, under damped, critically damped and marginally stable responsesb) At the output of the negative feedback system, cascade the transfer function
Explain what is meant by an overall heat transfer coefficient and explain what is mean by failing and what its effect will be on the value of the overall heat transfer coefficient.
what is the reason for the change in enthalpy between the throttle valve and the evaporator in a practical refrigeration cycle that is using R12 refrigerant.
A heat pump with a COP (coefficient of performance) of 2.8 is used to heat an air-tight house. When running, the heat pump consumes 5 kW of power
Analysis of the motion of swing including velocity and acceleration plots of all moving parts and projectile analysis of projectile eg: flight path, horizontal distance, deceleration and launch velocity
Verify that heating the wire may be treated as a lumped-capacity process, find the steady-state temperature of the wire and find how long it takes for the temperature of the wire to reach 100°C.
A car and a high -speed trian at constant speeds. three seconds after the train passes under the highway bridge the car crosses the bridge.
(a) Draw a schematic of the system and (b) determine if the inventor's claims are true.
A mixture of dry air and water vapor is at a temperature of 21C under a pressure of 101.3 kPa.The dew point temperature is 15C.(Ps= saturation pressure at 15C=1.7044 kPa;Pd=saturation pressure at 21C=2.4861 kPa) find humidity ratio and relative hu..
For the process where q= 62.5 kj/kg and wkcs= 60 kj/kg determine the energy change if the system mass is 2 kg.
Wheel of radius r is driven by an arm OA. It is driving (without slip) wheel of a radius r2 which is fixed to a drum of radius r1. Load G is attached to the rope which winds on the drum. Calculate the speed of load G if the arm OA moves at n rev/m..
what is the minimum distance d at which the brakes must be applied to avoid a collision? Treat the train as a particle and assume that the railroad tracks are rectilinear and horizontal.
Plot the total mass in the tank, in kg, and the amount of heat transfer, in kJ, versus the final quality x ranging from 0.2 to 1.0
