G=9.8 meter per second
2
F (required buoyancy)=m*g=2000*10=20000N
F (main gasbag provides)=ρ gV=19600N
F (balloonet provides)=ρ gV=9800N
m?=?2000㎏
A=9.8 meter per second
2
F?=?ma?=?19600N
Power=F+G=19600+20000=39600N that F is downward
S air bag floor space=2*(1800mm*1000mm)+2 (900*1110)=5.6 sq ms (air bag specification see below reckoning)
P air bag is required=(F/S)+101000pa (barometric pressure)+ρ water gh=0.113071Mpa
Compressed liquid carbon dioxide P=25.5Mpa
M=2.0 kilogram
Under P(reference standard conditions) * V (producing Co2)=P (air bag is required) * V(main gasbag volume)
0.101Mpa*(M/44)*22.4L=?0.113071Mpa*2000L
M=4.35908Kg
Therefore, in the technical program, adopt the compressed liquid carbon dioxide of 5Kg.
Under P(reference standard conditions) * V (5.0kg can produce Co2)=P (air bag) * V(main gasbag volume)
0.101Mpa*(5000/44)*22.4L=P*2000L
P (air bag)=2545*0.101/2000
=0.1285225Mpa
P air bag > P air bag is required
So, the pressure that in liquid carbon dioxide pressurized steel cylinder, gas has can be in the time that vehicle enters water filling air bag.
