Pot Equity value for different hands

Hi I'm new here and this is my first post.

I'm currently reading "Getting Started in Hold'em" by Ed Miller and finish reading the section on pot equity. It states that when your pot equity is much better than average you should raise for value, and mention that for Flush draw it is 35% on the Flop and down to 20% on the turn. What are the equity values for other hands like strait draw, I have made some searchs but can't fine any value for them.

Thanks,
Stephane
