A residential subdivision encompasses 1100 acres with a housing density of four houses per acre. Assume that a high-value reside

aleksandrvk [35]

Answer:

(a). The average daily demand of this subdivision is 2444.44 gallon/min.

(b). The design-demand used to design the distribution system is 2444.44 gallon/min.

Explanation:

Given that,

Area = 1100 acres

Number of house in 1 acres = 4

$\text{Number of house in 1100 acres} = 4\times1100$

$\text{Number of house in 1100 acres} = 4400$

Per house water demand = 800 g/day/house

(a). We need to calculate the average daily demand of this subdivision

Using formula for average daily demand

$\text{average daily demand}=house\times\text{Per house water demand}$

$\text{average daily demand}=4400\times800\ gallon/day$

$\text{average daily demand}=3520000\ gallon/day$

$\text{average daily demand}=\dfrac{3520000}{24\times60}\ gallon/min$

$\text{average daily demand}=2444.44\ gallon/min$

The average daily demand of this subdivision is 2444.44 gallon/min.

(b). We need to calculate the design-demand used to design the distribution system

Using formula for the design-demand

$\text{design demand}=(Q_{max})daily\times\text{fire flow}$

$\text{design demand}=1.64\times2444.4\times1000$

$\text{design demand}=4008816\ gallon/m$

Hence, (a). The average daily demand of this subdivision is 2444.44 gallon/min.

(b). The design-demand used to design the distribution system is 2444.44 gallon/min.

A patricle is accelerated uniformly from rest, so that after 10 seconds it has a speed of 15m/s find its acceleration and the di

grin007 [14]

Answer:

Its acceleration is 1.5 $\frac{m}{s^{2} }$ and the distance it has covered is 150 m.

Explanation:

Acceleration is a quantity that indicates the variation in speed of a moving body as time passes. That is, acceleration relates changes in velocity with the time in which they occur.

The average acceleration is defined as the relationship between the variation or change in the speed of a mobile and the time used in said change:

$acceleration=\frac{change in speed}{time}$

In this case:

change in speed= final speed - initial speed= 15 m/s - 0 m/s= 15 m/s
time= 10 s

Replacing:

$acceleration=\frac{15 \frac{m}{s} }{10 s}$

and solving you get:

acceleration= 1.5 $\frac{m}{s^{2} }$

Speed is a quantity that expresses the relationship between the space traveled by an object and the time used for it. This is:

$speed=\frac{distance}{time}$

So the distance can be calculated as:

distance= speed* time

In this case:

speed= 15 m/s
time= 10 s

Replacing:

distance= 15 m/s* 10 s

and solving you get:

distance= 150 m

Its acceleration is 1.5 $\frac{m}{s^{2} }$ and the distance it has covered is 150 m.
