A pool is to be filled with 60 m3 water from a garden hose of 2.5 cm diameter flowing water at 2 m/s. Find the mass flow rate of
stealth61 [152]

Answer:

Time= 6.12*10^4s

mass flow rate m=0.98kg/s

Explanation:

Given

Volume= 60m^3

diamter= 2.5cm= 0.025m

radius= 0.0125m

area A= πr^2

area A= 3.142*0.0125^2

area A= 4.9*10^-4m^2

the velocity of the flow 2m/s

<u>volume flow rate </u>

V=vA

V=2* 4.9*10^-4

V=9.82*10^-4 m^3/s

<u>Time taken to fill the pool</u>

time= volume/volume flow rate

time= 60/9.82*10^-4

time= 6.12*10^4s

<u>Mass flow rate </u>

m= density *volume flow rate

Assuming the density of water to be 997kg/m^3

m= 997*9.82*10^-4

m=0.98kg/s

A step up transformer has 250 turns on its primary and 500 turns on it secondary. When the primary is connected to a 200 V and t
Zina [86]

Answer:

2000 W

Explanation:

First of all, we need to find the output voltage in the transformer, by using the transformer equation:

\frac{V_1}{N_1}=\frac{V_2}{N_2}

where here we have

V1 = 200 V is the voltage in the primary coil

V2 is the voltage in the secondary coil

N1 = 250 is the number of turns in the primary coil

N2 = 500 is the number of turns in the secondary coil

Solving for V2,

V_2 = N_2 \frac{V_1}{N_1}=(500) \frac{200 V}{250}=400 V

Now we can find the power output, which is given by

P = VI

where

V = 400 V is the output voltage

I = 5 A is the output current

Substituting,

P = (400 V)(5 A) = 2,000 W

Leviafan [203]

Answer:

The plane's acceleration is 33.33 m/s²

Explanation:

The following equation relates velocity, v and acceleration of a moving body;

v = u + a·t

Where:

v = The final velocity of the body after time, t = 180 km/min

u = The initial velocity of the body just before the counting of the time = 0 m/s

a = The acceleration of the body during time, t = Required

t = The time of the motion = 1.5 minutes = 1.5×60 seconds = 90 s

v = 180 km/min = 180 km/min × 1000 m/km × 1/60 min/s = 3000 m/s

∴ 3000 m/s = 0 m/s + a × 90

a = \frac{3000 - 0 }{90}  = \frac{100}{3} = 33\tfrac{1}{3} \ m/s^2

Therefore, the plane's acceleration = 33.33 m/s².
