Water flows at 0.850 m/s from a hot water heater, through a 450-kPa pressure regulator. The pressure in the pipe supplying an up

grin007 [14]

Answer:

The velocity is $v_2= 0.45 \ m/s$

Explanation:

From the question we are told that

The initial speed of the hot water is $v_1 = 0.85 \ m/s$

The pressure from the heater $P_1 = 450 \ KPa = 450 *10^{3} \ Pa$

The height of the hot water before flowing is $h_1 = 0 \ m$

The height of bathtub above the heater is $h_2 = 3.70 \ m$

The pressure in the pipe is $P_2 = 414 KPa = 414 *10^{3} \ Pa$

The density of water is $\rho = 1000 \ kg/m^3$

Apply Bernoulli equation

$P_1 + \rho gh_1 +\frac{1}{2} \rho v_1^2 = \rho g h_2 + \frac{1}{2}\rho v_2 ^2$

Substituting values

$(450 *10^{3}) + (1000 * 9.8 * 0) + (0.5 * 1000 * 0.85^2) = (1000 * *9.8*3.70) + (0.5*1000*v_2^2 )$

=> $v_2^2 = \frac{ (450 *10^{3}) + (1000 * 9.8 *0 ) + (0.5 * 1000 * 0.85^2) -[ (1000 * *9.8*3.70) ]}{0.5*1000}$

=> $v_2= \sqrt{ \frac{ (450 *10^{3}) + (1000 * 9.8 * 0) + (0.5 * 1000 * 0.85^2) -[ (1000 * *9.8*3.70) ]}{0.5*1000}}$

=> $v_2= 0.45 \ m/s$

A rocket accelerates upward from rest at a rate of 5 m/s^2. At a height of 1000m, the engines burn out and it coasts the rest of

laila [671]

Answer:

Explanation:

Given

acceleration of rocket(a) $=5 m/s^2$

At h=1000 m rocket burn out

$v^2-u^2=2as$

$v^2-0=2\times 5\times 1000$

$v=\sqrt{10^4}=100 m/s$

(b) time to reach v=100 m/s

v=u+at

$100=0+5\times t$

$t=\frac{100}{5}=20 s$

(c)Rocket maximum altitude

$v^2-u^2=2as$

here u=100 m/s

v=0

$a=9.8 m/s^2$

$s=\frac{v^2}{2g}$

$s=\frac{100^2}{2\times 9.8}$

[tex]s=510.204

Therefore maximum altitude=510.204+1000=1510.204 m

What is the net force acting on a 50-kg object that accelerates at a rate of +3.5 m/s/s?

Nostrana [21]

Answer:

<h2>The answer is 175 N</h2>

Explanation:

The force acting on an object given it's mass and acceleration can be found by using the formula

force = mass × acceleration

From the question we have

force = 50 × 3.5

We have the final answer as
