Air at a dry bulb temperature of 40C and a wet bulb temperature of 20C is first heated in a heater to a dry bulb temperature of 90C. Then it is passed through a bed of apricot slices to dry them. The air existing from the bed is at a dry bulb temperature of 60 C. It is then passed through a dehumidifier to reduce its relative humidity to 10%. Clearly show the various paths of the process on a psychrometric chart. Determine (a) the amount of moisture removed from the bed per kg of dry air (b) the amount of moisture removed in the dehumidifier per kg of dry air.

A particle moves with speed of 0.8c at an angle of 30 degrees to the x-axis, as determined by O . What are the speed and direction of the particle as seen by a second observer O’, moving with a speed of −0.6c along the common x-axis? We know that: u=0.8c v=-0.6c Determine u’ (speed of the particle) and the direction of the particle as seen by the second observer (O’)

A random sample of 16 junior managers in the offices of corporations in a large city center was taken to estimate average daily commuting time for all suchmanagers. Suppose that the population times have a normal distribution with a mean of 87 minutes and a standard deviation of 22 minutes. (a) What is the standard error of the sample mean commuting time? (b) What is the probability that the sample mean is fewer than 100 minutes? (c) What is the probability that the sample mean is more than 80 minutes? (d) What is the probability that the sample mean is outside the range 85 to 95 minutes?

In this project you will analyze and simulate the control system of an Unmanned Free-Swimming Submersible (UFSS) vehicle. The heading control system (Figure 1) steers the vehicle. A heading command is received as input and this input and the feedback from the submersible’s heading and yaw rate are used to generate a rudder command that steers the vehicle.

Determine the transient response parameters of the system i.e. percent overshoot, damping ratio, natural frequency, peak time, rise time and settling time. 3. Model the block diagram of Figure 1 in Simulink. Simulink does not allow a transfer function where the numerator is of higher order than the denominator. Therefore, you need a workaround. Hint: H(S) -s can be moved outside its loop using one of the properties of chapter 5 for control system block diagram reduction. Apply a step input and run the Simulink model simulation to plot the step response. Compare the system step response obtained from Simulink to the results obtained from MATLAB 4. Use MATLAB to plot the root locus of this system. Comment on the results of the root locus. What is the range of the system gain for stability?

2. (Based on a question from the text by Tipler) In Episode 5 of Star Wars, the Empire’s spaceships launch probe droids throughout the galaxy to seek the base of the Rebel Alliance. Suppose a spaceship moving at 2.3 x 10 m/s toward Hoth (site of the rebel base) launches a probe droid toward Hoth at 2.1 × 108 m/s relative to the spaceship -(a) According to Galilean Relativity what is the speed of the probe droid relative to Hot h? -(b) In terms ofspecial relativity if rebel astronomers are watching the approaching spaceship through as telescope, will they see the probe before it lands on Hoth? (c) According to Special Relativity, what is the speed of the probe droid relative to hot h?
