A composite plane wall consists of a 5-in.-thick layer of insulation (ks = 0.029 Btu/h*ft*°R) and a 0.75-in.-thick layer of sidi

Leno4ka [110]

We have that the <em>temperature </em>at the <em>interface </em>of the two <em>layers</em>, in °F, and (b) the rate of heat transfer through the wall in Btu/h*ft^2 of surface area is given as

a)  $T_i-12.11^oF$

b) $H_r=3.80 btu/hft^2\\\\$

From the question we are told

A composite plane wall cons<em>i</em>sts of a 5-in.-thick layer of insulation (ks = 0.029 Btu/h*ft*°R) and a 0.75-in.-thick layer of siding (ks = 0.058 Btu/h*ft*°R).

The inner temperature of the insulation is 67°F. The outer temperature of the siding is -8°F.

<h3>Interface Temperature</h3>

Generally the equation for the Terminal resistance is mathematically given as

$R_1=\frac{t_1}{k_1A}\\\\R_1=14.3667hft^2R/btu\\\\Also\\\\R_2=\frac{t_2}{k_2A}\\\\R_2=1.077hft^2R/btu\\\\$

$Heat transfer rate\\\\H_r=\frac{67-8}{15.444}\\\\H_r=3.80 btu/hft^2\\\\$

a)Interface Temp(T_i)

$T_i=\frac{67-t_2}{R1}=3.820$

bonufazy [111]

Answer:

Net heat transfers: during summer = 52.253 W/m^2 during winter = 119.375 w/m^2

Explanation:

Given data :

Room temperature throughout the year = 20⁰c = 293 k

Room temperature during summer = 27⁰c = 300 k

Room temperature during winter = 14⁰c = 287 k

surface temperature of a person throughout the year = 32⁰c = 305 k

coefficient of heat transfer by natural convection (h)= 2 w /m^2 k

emissivity = 0.9

An explanation to the condition of feeling chilled during the winter and comfortable during summer can be explained with the calculation below

The heat transfer from the surface body of a person the the room is carried out by convection and this can be calculated as

q = hΔt = 2 * ( 305 - 293) = 2 * 12 = 24 w /m^2

also calculate heat transfer through radiation using this formula

$q_{rad} =$ εσ [ (Temperature of body)^4- (temperature of room at each season)^4 ]

ε = 0.90,(emissivity) σ = 5.67 *10^-8 w/^2 . k ( Boltzmann's constant)

during summer :

$q_{rad}$ = (0.90)*(5.67*10^-8)* ( 305^4 - 300^4 ) = 28.253 W/m^2

therefore the net heat transfer during the summer = 24 w/m^3 + 28.253 W/m^3 = 52.253 W/m^2

During winter :

$q_{rad}$ = (0.90)*(5.67*10^-8) * ( 305^4 - 287^4 ) = 95.375 W/m^3

therefore the net heat transfer during the winter

= 24 w/m^3 + 95.375w/m^3 = 119.375 w/m^2

A ballistic pendulum consists of a 3.60 kg wooden block on the end of a long string. From the pivot point to the center‐of‐mass

Pavel [41]

Answer:

17.799°

Explanation:

When the bullet hits the block at that time the momentum is conserved

So, initial momentum = final momentum

$P_i=P_f$

So $28\times 10^{-3}\times 210=(3.6+0.028)v_f$

$v_f=1.6207\ m/sec$

Now energy is also conserved

So $\frac{1}{2}\times (3.6+0.028)\times 1.6207^2=(3.6+0.028)\times 9.81\times 2.8(1-cos\Theta )$

$cos\Theta =0.8521So\ \Theta =17.799^{\circ}$
