Problem #$1$:

The $0\mathrm{.}5-$in$.-$diameter hose shown in the following figure can withstand a maximum pressure

within it of $200$ psi without rupturing. Determine the maximum length, L$,$ allowed if the friction

factor is $0\mathrm{.}022$ and the volumetric flow rate is $0\mathrm{.}010f\frac{t^3}{s}.$ Neglect minor losses. The fluid is water.

Write and simplify the Bernoulli equation for this process.

If it collapses and the pressure within it is lower than $10$ psi below atmospheric pressure and the

friction factor is $0\mathrm{.}015.$ Explain if the length decreases or increases.
