1. Consider the transfer function model:G(s) =(s+ 10)s4+ 10s3+ 35s2+ 74s+ 120(0.1)(a 10 pts.) Calculate poles and zeros of this transfer function.(b 15 pts.) Approximate this high-order model by a second-order plus time delay modelG1(s), and use MATLAB to show the step response ofG(s) andG1(s). (Note: Usingthe rst method. G1(s) should have two poles and no zero

Afour cylinder four-stroke in-line engine has a stroke of 160mm, connecting rod length of 150mm, a reciprocating mass of 3kg and its firing order is 1-3-4-2. the spacing between cylinders is 100mm. i. show that the engine is in balance with regard to the primary inertia forces and primary 3. a and secondary inertia couples. li determine the out of balance secondary inertia force ii. propose ways of balancing this out of balance force and discuss the challenges that will arise

Give heat transfer applications for the following, (i) gas turbines (propulsion) ) gas turbines (power generation). (iii) steam turbines. (iv) combined heat and power (chp). (v) automotive engines

Air is flows through an adiabatic nozzle with an inlet pressure of 400 psia at a temperature of 300°f and a velocity of 20 ft/s. the outlet pressure is 40 psia and the velocity is 800 ftl/s. determine the outlet temperature of the air using: a) property tables b) specific heat (using the specific heat value for air at 300°f)
