Convert 1 cal/(m^2 * sec * °C) into BTU/(ft^2 * hr * °F)

Crazy boy [7]

Answer:

$1\ \frac{\text{cal}}{m^2\times sec\times ^\circ C}=0.03926\frac{\text{BTU}}{ft^2\times hr\times ^\circ F}$

Step-by-step explanation:

To find : Convert $1\ \frac{\text{cal}}{m^2\times sec\times ^\circ C}$ into $\frac{\text{BTU}}{ft^2\times hr\times ^\circ F}$

Solution :

We convert units one by one,

$1\text{ m}^2=10.7639\text{ ft}^2$

$1\text{ sec}=\frac{1}{3600}\text{ hour}$

$1\text{ cal}=0.003968\text{ BTU}$

Converting temperature unit,

$^\circ C\times \frac{9}{5}+32=^\circ F$

$1^\circ C\times \frac{9}{5}+32=33.8^\circ F$

So, $1^\circ C=33.8^\circ F$

Substitute all the values in the unit conversion,

$1\ \frac{\text{cal}}{m^2\times sec\times ^\circ C}=\frac{0.003968}{10.7639\times \frac{1}{3600}\times 33.8}\frac{\text{BTU}}{ft^2\times hr\times ^\circ F}$

$1\ \frac{\text{cal}}{m^2\times sec\times ^\circ C}=\frac{0.003968}{0.101061}\frac{\text{BTU}}{ft^2\times hr\times ^\circ F}$

$1\ \frac{\text{cal}}{m^2\times sec\times ^\circ C}=0.03926\frac{\text{BTU}}{ft^2\times hr\times ^\circ F}$

Therefore, The conversion of unit is $1\ \frac{\text{cal}}{m^2\times sec\times ^\circ C}=0.03926\frac{\text{BTU}}{ft^2\times hr\times ^\circ F}$

Find an equation for the surface consisting of all points p for which the distance from p to the x-axis is 5 times the distance

guajiro [1.7K]

Distance from P to the x-axis = 2x distance from P to the yz-plane

Distance to the x-axis of a point P=(x,y,z) is (y^2+z^2)^1/2 
Distance to the yz-plane of a point P=(x,y,z) is x 

So your equation is: 
(y^2+z^2)^1/2 = 2x 
=> y^2 + z^2 = 4x^2 
=> y^2 + z^2 - 4x^2 = 0

Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions.

ANTONII [103]

Answer:

$50\ games$

Step-by-step explanation:

Let

x-----> the total number of games the team played this year

Using proportion

$\frac{32\%}{16}=\frac{100\%}{x}\\ \\x=16*100/32\\ \\x=50\ games$
