## Announcements

<9/25/2008> Homework 4 and Design Project 1 have been posted.

If you do not have the Janna textbook, you will need the following properties for problem 13:

viscosity of propylene glycol = 88x10^-5 lbf-s/f^2

SG propylene glycol = 0.968

density of water = 62.4 lblm/ft^2 (sea level).

## Homework Solutions

Homework 5: 4.19d x = 1.45 m, 4.52 , 5.16: Visualize this problem using Figure 5.6a, use 1m of water head for a factor of safety (see page 260) NPSHa = 1.258m , z_s < 3.54m 5.17 17.3 HP delivered to the liquid
