Asimple supported beam at x0 = 0 and xn = l with a uniform load w and the
vertical deflection v(x) is described by the boundary value problem

wx, v(0) = 5, v(l) = 100
where l is the length of the beam, e represents the young’s modulus of the material from which
the beam is fabricated and i is the second moment of area of the beam’s cross–section. suppose
l = 15 m, e = 210 kn/m

, i = 370.5 m2
and w = 9.8 kn/m. use the shooting method to
approximate the vertical deflection, v(x) with the step size, h = 3, the first guess, z0 = 10 and
the second guess, z0 = 5.

For the closed feedwater heater below, feedwater enters state 3 at a pressure of 2000 psia and temperature of 420 °f at a rate of ix10 ibhr. the feedwat extracted steam enters state 1 at a pressure of 1000 psia and enthalpy of 1500 btu/lbm. the extracted er leaves at an enthalpy of 528.7 btu/lbm steam leaves as a saturated liquid. (16) a) determine the mass flow rate of the extraction steam used to heat the feedwater (10) b) determine the terminal temperature difference of the closed feedwater heater
