The change in force per unit area, for steady, incompressible viscous flow through a straight horizontal pipe depends on the pipe length, the average velocity, the fluid viscosity, the pipe diameter, the fluid density, and the average \"roughness\" height. Determine a set of dimensionless groups that can be used to correlate data.

Consider a group of waves that have a distribution of k values such that the net signal is given by y = acos(kx) + acos(k+kx) + ... + acos(k+n-1kx) (5) a. What is k, the average k value in the band? b. What is the bandwidth k? c. In the limit that k is small, show that y can be written as a sinc function. d. In this same limit, what is the spatial width of the wave group x in terms of k? Hint: Find the first zero of the sinc function.

Steam at 134 kPa and 85% quality enters a radiator. The steam is condensed as it flows through the radiator and leaves as condensate at 90°C. If the radiator is to have a heating capacity of 2.65 kW ($Q$), how many kilograms per second ($m$) of steam must be supplied to the radiator? Hints: Review equations: 2-5, 2-6, 2-7, 2-56, Figure 2-21 and Table 2-1 SI Thermodynamic properties of Water (found at the end of Chapter 2) also kJ/kg (kg/s) = kJ/s $\Delta H$ Steps: solve for $h$ (or $h_1$ for this problem), $h_2$ is the condensate (saturated liquid), then solve for $m$ in the $Q$ equation. The columns in the table clearly show: $h_f$ and $h_g$ and $h_{fg}$ for the two set points (90°C and 134 kPa)
