Hello can someone explain me how can I get the value of (6340) because when I try to solve the given values on the book I get (6423.980075) when I round it off it is still not the right answer can someone help me please enter image description here

ρ=44.5 lb/ft³ g=32.2 ft/sec² ΔP=100 convert to lb/ft² = 14400 lb/ft²

My Solution √(2x32.2)(44.5)(14400)=6423.980075 Please tell me how can I get 6430 instead of 6423 help

  • $\begingroup$ If you already solved out your first problem perhaps you could add your solution as an answer, or mark the existing answer as correct and accepted if it was helpful? $\endgroup$ Commented Feb 13, 2020 at 15:16

  • $\begingroup$ 6430 is pretty suspiciously round, given the numbers that allegedly went into it. I expect that the authors have just used some unreasonable rounding somewhere, or a slightly odd value for one of the constants. The final area ends up being within 0.000001in^2 of the given answer. $\endgroup$ Commented Feb 14, 2020 at 8:05
