##### Reference no: EM131249251

A particle of mass m slides without friction inside a three-dimensional conical funnel, whose walls have unit slope and whose center axis is vertical (Figure 10.26). If the particle is launched inside the funnel at height h and horizontal speed s0, find the vertical speed of the particle when it reaches the bottom of the funnel. #### Changes in kinetic and potential energies is zero

Ten cubic feet of air is cooled at a constant pressure of 80 psi. The initial temperature is 180 0F and the final temperature is 100 0F. Assume air is an ideal gas, Cp = 0.241
