1 answer:

Gemiola [76]3 years ago

6 0

Answer:

Ventilation systems are crucial. Their purpose is to avoid explosions by removing flammable gases. The Small Vessel Regulations require that all gasoline-powered boats, constructed in a way that would entrap vapours, must have at least two ventilation ducts fitted with cowls to remove the vapours. ...

RUDIKE [14]

Answer:

$$\begin{align*}

P(Y−X=m|Y>X)=∑kP(Y−X=m,X=k|Y>X)=∑kP(Y−X=m|X=k,Y>X)P(X=k|Y>X)=∑kP(Y−k=m|Y>k)P(X=k|Y>X).

Explanation:

P(Y−X=m|Y>X)=∑kP(Y−X=m,X=k|Y>X)=∑kP(Y−X=m|X=k,Y>X)P(X=k|Y>X)=∑kP(Y−k=m|Y>k)P(X=k|Y>X).

Using the degree day method calculate the annual kwh use in springfiled il with a heat loss of 12kwh an inddor twmperature of 7

vladimir2022 [97]

Answer:

The correct solution is "21024 KWh/degree day".

Explanation:

The given query is incomplete. Below is the attachment of complete query is provided.

The given values are:

Indoor design temperature:

= 70°F

Now,

According to the question,

The heat loss annually will be:

= $12\times 24\times 365$

= $105120 \ KW$

Degree days will be:

= $75-65$

= $5$

Hence,

Annual KWh use will be:

= $\frac{Heat \ loss \ annually}{degree \ days}$

On substituting the values, we get

= $\frac{105120}{5}$

= $21024 \ KWh/degree \ day$

P1.30 shows a gas contained in a vertical piston– cylinder assembly. A vertical shaft whose cross-sectional area is 0.8 cm2 is a

iogann1982 [59]

Answer:

1.737 kJ

Explanation:

Thinking process:

Step 1

Data:

Area of the shaft = 0.8 cm²

Combined mass of shaft and piston = (24.5 + 0.5) kg

= 25 kg

Piston diameter = 0.1 m

External atmospheric pressure = 1 bar = 101.3 kPa

Pressure inside the gas cylinder = 3 bar = 3 × 101.3 kPa

g = 9.81 m/s²

Step 2

Draw a free body diagram

Step 3: calculations

area of the piston = 0.0314 m²

Change in the elevation of the piston, $\deltaz$

$\delta$ z = $\frac{PE}{mg}$

= $\frac{0.2*10x^{3} }{25*9.81}$

= 0.82 m

Next, we evaluate the work done by the shaft:

$W_{s} = F_{s} Z$

= (1668) ( 0.082)

= 1. 37 kJ

Net area for work done = A (piston) - Area of shaft

= $\pi*(0.1)^{2} - 0.8 cm^{2}$

= 77.7 cm²

= 0.007774 m²

Work done in overcoming atmospheric pressure:

Wₐ = PAZ

=101.3 kPa * 0.007774 * 0.82

= 0.637 kJ

total work = work done by shaft + work to overcome atmospheric pressure = 0.367 + 1.37

= 1.737 kJ Ans
