P=WH, H=P/W, H=48/.8=60.

Hi, @Brijendra.

How you take 4.8 as 48?

Hello, @Brijendra.

How you take pressure 4.8 to 48?

@Brijendra.

Tell me how you converted 4.8 to 48?

Here, it is converted it in newton by multiplying 10.

Another way to do it is, 1st convert 4.8kg/cm2 into kg/m2 by multiplying it with 10000.
Ten again multiply by 10 to get in N/m2, then find out the specific weight.
=> 8 * 1000 * 10 now divide 480000/8000.
You will get 60 as an answer.

Explain briefly!

Pressure = W * H.
4.8 * 10^3 = sp. grvty * dnsty * H.
4800 = 0.8 * 1* H.
H = 6000cm = 60m.

H = p/w.
= 48/.8,
= 60.

Answer must be 60m. I agree.

BASTARD said:   8 years ago
PRESSURE=(UNIT WT.)*(HEIGHT).

4.8 = (0.8)*(1000/100^3)*(H),
H = 6000 cm.
H = 60 m.
