?

I might be leaving...

So, I met a girl about 4 days ago and I asked her for her e-mail.

I then later sent an e-mail asking how was her day, and she did reply, and I told her after that - that I wanted to see her again - and she never has replied since.

Should I just move on, I mean it's been about 3-4 days since I've told her that.

I liked her, and I thought she liked me - I made her laugh and initiated conversations, we both were getting along well, but where did she go?

should I? i have a pic of me on the avatar thing...

what's next?

and yet they don't show up! That pisses me off!

I'm angry!

"Girl, you're beautiful and you don't even know it!"

Just thought I'd put that out there for all the girls. ;) lol

I need to study more. A whole lot more.

Water at 15°C is pumped from a large reservoir to an elevated water storage tank through a 8 cm diameter pipe.

The water surface in the tank is located at an elevation of 26 m above the water surface in the reservoir.

Energy losses due to friction and pipe fittings are equivalent to a total of 18 m of water.

Determine how much energy must be added to the system (in J/kg) so that a constant pumping rate of 0.040 m3/s is maintained.

Answer:

a pipe with a diameter of 8cm and has a flow rate of 0.040 m^3/s has a velocity of 7.9577 m/s.

and you know the energy conservation equation is (v^2)/2 + g*h + P/rho

(7.9577^2)/2 + (18+26)*9.81 = 463.302 J/kg .... Theres no pressure difference

=========BUT, that's not the right answer...===============

So, what am I doing wrong?

Hi,

I'm using the Bernoulli equation and I'm given the head loss as 11m of water.

I just wanted to know if its possible to convert this into joules given that you know the density of water is 999.1 kg/m^3 at 15 degrees Celsius?

Thanks.

A student wishes to analyze an unknown sample, which contains both calcium sulfate and calcium carbonate. The student weighs a 5.000-g sample of the unknown and treats it with 30.0 mL of 1.00 N hydrochloric acid, an amount that was in excess. The excess acid was titrated with 0.155 N NaOH (aq), requiring 25.55 mL to reach equivalence. Determine the percent by weight CaCO3 in the sample.

Or if you don't have any siblings, who do you find annoying related to you?

My older brother is 26 and still acts like a child. :'( So annoying.

because there is something better that's coming along the way? Something better in store for you?

I think so.

I'll be in a lab working with chemicals. LOL

would that mean they care about you?

For me, it's the immune/ nutrition drink song... hi ho hi ho.. off to work we go!

God I hate that song.
