Bernoulli + Kutta condition + proper design (must have sharp trailing edge)
the trailing edge of all airfoils must be sharp. Kutta condition says that
the top and bottom flow of the airfoil must meet at the sharp edge, that is
, flow can not wrap around the sharp edge due to viscosity. Thus, the flow
on top of the airfoil must travel faster than the flow below the airfoil for
a properly designed airfoil under correct angles of attack. Then, with
Bernoulli's theory, you get pressure difference, a... 阅读全帖

Cheap natural gas and increasingly competitive labor costs are bringing

As the only industrialized superpower not decimated by World War II, the

number has shrunk to 18%. We make American Girl dolls in China, Levi's jeans

Is Your Fuel Gauge Not Working?
1. Locate the fuel tank of your car. There should be a wire near the tank
with a tan color – this is the “fuel sender feed wire”, which indicates
to the fuel gauge how much gas you have left in the tank of your car.
Disconnect the wire at the base to test it.
2. When the wire is disconnected and the node hangs loosely in air, the
needle of the fuel gauge should be reading above full. If the node is

I am not sure over flow is your problem. Taking a bath is your problem.
When you shower, water is flow down at a much smaller rate and pressure,
after you take a bath, you unplug the drain, a lot of water is coming down
at the much faster rate and pressure. That is a small leak in the drain line
(not necessary in the over flow part) that need to fixed.
If you have warranty, you should call them first, if they don't fix it, you

net cash flow已经是把租金算在你里面了。
我估计这个net cash flow没把owner自己的人工算进去。
不过即便是即便减掉10万的人工,只有8万的cash flow,still too good to be true.
想想如果有个35万的房子,房租能收回8万每年,是不是一下就被抢掉了。(这里假设这个店可以一直开下去)
cash flow也没有包括设备折旧,不过估计没有多少钱。
他如果要卖的话,应该是把他的book给你看的。仔细看看。
只卖设备那就成了liquidation value了,在这里没有意义。
现在是卖一个ongoing business。既然是ongoing business,这个租约应该是非常重要。

On the surface, these are impressive results.

Or 1.60/per year.
Biggest problem: They have around 700 million loans need to roll over in
March/20111. If they can successful roll over the loan, the stock should
trade much higher(over $5), otherwise, the stock could crashed down to as
low as 1.50 in my estimate.

In Q3, we generated $26 million of positive free cash flow (cash flow from

This is a new record for positive cash flow generated in any quarter. Our
total cash at quarter end was $796 million
