Question

Please find thickness

Pressure (PSI) Hoop Stress Thickness in. Longitudinal Stress Thickness in. 500 1000 1500 1000 500 Average Thickness Average Thickness: in.

Answer 1

$\small \sigma$_h = pd/2t

for Design, $\small \sigma$_h$\tiny \geq$ pd/2t

t $\tiny \geq$ pd / 2$\small \sigma$_h as per hoop stress

Similarly as per longitudinal stress, t $\tiny \geq$ pd / 4$\small \sigma$_L

Diameter, d = 2 in

Pressure (PSI)	Hoop Stress ($\small \sigma$h ) (PSI)	Hoop Stress Thickness (th) (in)	Longitudinal Stress ($\small \sigma$L ) (PSI)	Longitudinal Stress Thickness (tL) (in)
500	6031.41	0.083	2897.54	0.086
1000	11426.44	0.088	5439.35	0.092
1500	17880.05	0.084	8525.21	0.088
1000	1948.34	0.513	5680.60	0.088
500	6100.34	0.082	2493.08	0.100
Average Thickness		0.170		0.091

As per hoop stress, thickness t = 0.17 in

As per longitudinal stress, thickness t = 0.091

Hence Average Thickness, t =0.131 in
