With the average home in the capital selling for 19,548 yuan a meter in November, a tiny mobile home built by a 24-year-old office worker is creating a stir(震动) online.

Dai Haifei built the 6-square-meter pad(住所) because he could not afford to buy or rent in the capital.

Dai’s new home costs him 6,400 yuan and he has been living in it for nearly two months in courtyard at Chengfu

Road, Haidian district.

Dai, who is one of the millions of migrants who moved to the capital from other parts of China seeking a better

life and better job, said he realized his financial burden had become too great.

The Hunan native said he simply could not make ends meet(收支相抵) when he became an intern at a

Beijing-based construction design company in 2009.

“I rented a home at the very beginning--a small room in an apartment that cost me about 900 yuan per month,”

said Dai in an interview with local media. “It was too expensive for me. ”

Dai’s father works on a construction site in his hometown and his mother is a cleaner.

Dai, who ended up becoming a formal employee of the company, figured out his own way to solve the

problem---with inspiration from a housing design project at his company’s exhibition early this year.

The project, named“An egg given birth to by the city”, included a series of egg-like movable houses, with a

karaoke house, chair house and trader’s house in it.

Dai, who borrowed 6,400 yuan from an older cousin and who got additional help from several friends, decided to

make one of his own. He spent nearly two months building his“egg house”in his hometown, a village in southeast

Hunan that is around 1,700 kilometers from Beijing.

气体压强会随着流动速度而改变.如图所示,当有同学在桌子一侧向放在桌面上的一枚1角硬币水平吹气时(即有高速的气流通过硬币上方),硬币会跳起.

(1)已知当时大气压为p0(即静止空气的压强),硬币质量为m,上表面面积为A.为使硬币跳起,上方流动空气压强的最大值为p=______.

(2)某同学查阅了相关资料:忽略高度影响,流动的空气压强与流速满足

1
2
ρv2+p=常量(其中ρ为空气密度).根据(1)中的物理量和上述公式可知,实验时此常量大小为______,并且在已知空气密度ρ的情况下,可计算得到硬币起跳时上方空气流速至少为v=______.

(3)若吹气时同学的嘴张开面积为S,则估算同学的吹气功率的表达式为______.
