018 10.0 points A fireman standing on a 14 m high ladder
operates a water hose with a round nozzle of
diameter 2.13 inch. The lower end of the hose
(14 m below the nozzle) is connected to the
pump outlet of diameter 3.15 inch. The gauge
pressure of the water at the pump is
(abs)
= 57.3 PSI = 395.07 kPa.
Calculate the speed of the water jet emerg-
ing from the nozzle. Assume that water is an
incompressible liquid of density 1000 kg/m
3
and negligible viscosity. The acceleration of
gravity is 9.8 m/s2
Answer in units of m/s

what grade

Step-by-step explanation:

linearly: 8560 bacteria

exponentially: approximately 75233 bacteria

step-by-step explanation:

assuming it is not exponential (we would have some really complicated logarithms), let's say it is linear. then, after 5 hours, it increased by 1200 bacteria, so every hour it increases by 240 bacteria. this means that after 19 hours, we get 19 * 240 + 4000 bacteria or 3800 + 760 + 4000 = 7800 + 760 = 8560 bacteria.

because it says round your answer, i will do this exponentially (with a calculator, of course). first, we need to find how much it multiplies by every hour, by taking the 5th root of 52/40 or 13/10. this is approximately 0.167. we still need to add 1 to this, because we are multiplying by that number, not adding that amount of the number. now, we just calculate 4000 * (1.167)^19. use a calculator to get approximately 75232.6, or 75233.
