3. (25 pts.) Compute the first four polynomial interpolations (linear, quadratic, etc.) for the function $(x) = 1 - exp(-x) with evenly spaced data on the interval x € (0,3). Make a plot of the
interpolation and the function itself using MATLAB. Also make a plot of the difference between
the function and the interpolant. You can either work it out by hand or by writing a program. If
you work it out by hand, include the values of all the coefficients for each interpolation formula.

When at a point two solid phase changes to one solid phase on cooling then it is known as a) eutectoid point b) eutectic point c) peritectic point d) peritectoid point

What difference(s) did you notice using a pneumatic circuit over hydraulic circuit.explain why the pneumatic piston stumbles when it hits an obstacle.

Air is to be cooled in the evaporator section of a refrigerator by passing it over a bank of 0.8-cm-outer-diameter and 0.4-m-long tubes inside which the refrigerant is evaporating at -20°c. air approaches the tube bank in the normal direction at 0°c and 1 atm with a mean velocity of 4 m/s. the tubes are arranged in-line with longitudinal and transverse pitches of sl- st 1.5 cm. there are 30 rows in the flow direction with 15 tubes in each row. determine (a) the refrigeration capacity of this system and (b) pressure drop across the tube bank. evaluate the air properties at an assumed mean temperature of -5°c and 1 atm. is this a good assumption?
