A canal connects a reservoir to a town. This canal supplies water to the town. Last summer, the town is supplied with water at an average rate of 2.7m^3s^-1. This canal is 51km long and 9.2m wide. In the daytime, the average power from the Sun that is absorbed per unit area by the surface of the water is 900Wm^-2. The temperature of the water does not change.
The density of water is 1000kg^m-3 and the specific latent heat of vaporisation of water is 2.26 x 10^6 Jkg^-1. What is the rate that the water has to be supplied from the reservoir?3 AnswersPhysics1 decade ago

Hi, I'm currently near graduation and am expected to hand in a self-directed project. I've chosen to write a collection of poems, but unfortunately I find that I feel uncomfortable writing poems, esp those with rhythm.
I need your help in recommending some types of poems which are easy to handle, and without the need for rhythm.
An example would be a terza rima.
Oh, and for a modern sonnet, can I omit the rhyme and rhythm ? Just 14 lines with 10 syllables each?
Thanks a lot!1 AnswerPoetry1 decade ago
