Hi! I have the following equation for the entrance loss from an open channel to a pipe, but I'm not sure how it was derived: hloss = K*(V2^2 - V1^2)/2g I have always seen entrance losses as: K*(V^2)/2g, but why is the channel flow velocity considered in the equation above. Thanks...

this is not a lie. You know that channel that scrolls a guide for what's on TV? I think it is called the TV Guide Channel. I swear to God that right now as I'm typing this, on channel 7 from 6 to 6:30pm is the following show and it really gets me upset: Cox connecting with kids where is the FCC...

Favorite "intellectual" TV channel What "intellectual" TV channel do you enjoy the most?

Clear Channel... I know that it isn't really current news but I have heard quite a bit of bad press in regards to Clear Channel. a lot of it seems to be embellished from what I have gathered. There seem to be two main complaints. One: Clear Channel is partisan and it's radio news, among...

Seriously, did anyone see their most recent program called Voyage to The Planets and Beyond? It's totally ridiculous! The program is about a manned voyage to 5 of the 9 planets and close pass by the sun, a voyage that alone takes over 1200 days. I'll list some of the outragous events that take...

Does anyone know why on some cable channels I didn't subscribe, I can still see something (with a lot of distortion and noise), while I can't see anything at all in some others? How are the signal modulated and encoded? Are they encrypted? How come some channels are encoded that I can still...

not sure if this has aired before, but it mentioned Gumble/SC Fi's (in 2003,forget when) This was excellent--at least Cosmos 96 was debunked (James Oberg even reaches this 'conclusion',yet begins his own 'conspiricy theory' ---mindboggling; perhaps his 'balloon solutions' should be...

Measurements with microelectrodes have shown that a 0.30-nm-diameter potassium ion (K+) channel carries a current of 1.8 pA. How many potassium ions pass through if the ion channel opens for 1.0 ms? What is the current density in the ion channel? I am completely lost for this one...

According to my TiVo guide this Wednesday at 10PM the show "Modern Marvels" on the History Channel will have a program about hydrogen as a fuel. Those interested may want to check it out to see if it indeed covers this topic. Cliff

Science Channel showed last night a documentary called "Black Sky" that was a 2 hour behind the scenes look at the operations at Scaled Composities and a short history of Burt Rutan. They have footage of the construction of the carrier plane White Knight and the test flights of Space Ship One...
