Question

I want to develop a program which will calculate the total pressure and the hydrostatic pressure on a submerged vehicle in atmospheres. Associate this program with a button on a worksheet. Ask the user to input the specific gravity of the fluid and the submersion depth in feet in an input box. Set a variable for the acceleration of gravity in your code, and then use that variable in your equations (that way, you can change the variable's value once and get updated calculations everywhere the variable is used. This is good programing practice). Set a variable for the atmospheric pressure and use that variable in the program: set this pressure to 1 atm. Calculate both total pressure and hydrostatic pressure, and report them back to the user in a message box. DO NOT ABOUT FORGET THE UNITS in either your calculation or the output statement to the user! 3.

the specific programming language to do this with is Visual Basic

what formula? specify what you mean

Answer 1

Hydrostatic pressure= density or specific gravity *gravity *submersion height.

Total pressure=hydrostaic pressure + atmospheric pressure.

Private Sub SurroundingSub()
Dim g As Double = 9.8
Dim spGravity As Double = Convert.ToDouble(textBox1.Text)
Dim depth As Double = Convert.ToDouble(textBox2.Text)
Dim atmPressure As Integer = 1
Dim hydrostaticPressure As Double = spGravity * g * depth
Dim totalPressure As Double = atmPressure + hydrostaticPressure
MessageBox.Show("The hydrostatic pressure is " & hydrostaticPressure & " atm" & "and total pressure is " & totalPressure)
End Sub

Please rate it if the above solution helps you in any way or if you have any concerns comment it, I will help you through again.
