Answer:
L = 46.35 m
Explanation:
GIVEN DATA
\dot m = 0.25 kg/s
D = 40 mm
P_1 = 690 kPa
P_2 = 650 kPa
T_1 = 40° = 313 K
head loss equation
![[\frac{P_1}{\rho} +\alpha \frac{v_1^2}{2} +gz_1] -[\frac{P_2}{\rho} +\alpha \frac{v_2^2}{2} +gz_2] = h_l +h_m](https://tex.z-dn.net/?f=%5B%5Cfrac%7BP_1%7D%7B%5Crho%7D%20%2B%5Calpha%20%5Cfrac%7Bv_1%5E2%7D%7B2%7D%20%2Bgz_1%5D%20-%5B%5Cfrac%7BP_2%7D%7B%5Crho%7D%20%2B%5Calpha%20%5Cfrac%7Bv_2%5E2%7D%7B2%7D%20%2Bgz_2%5D%20%3D%20h_l%20%2Bh_m)
where
density is constant
head is same so,
curvature is constant so
neglecting minor losses
we know
is given as
therefore
V = 25.90 m/s
for T = 40 Degree, 
Re = 4.16*10^5 > 2300 therefore turbulent flow
for Re =4.16*10^5 , f = 0.0134
Therefore
L = 46.35 m
Answer: you’re bussy *in french accent*
Explanation:
it is very wide as you can see *also in french*
Answer:
I think answer is The type of load, Environment factors
Answer:
1. 3.75
2. 1.39 ft
Explanation:
The mechanical advantage is the ratio of the resistance force to the effort force.
MA = 75 lb / 20 lb
MA = 3.75
The sum of the torques about the fulcrum equals zero.
∑τ = Iα
(20 lb) (5.2 ft) − (75 lb) x = 0
x = 1.39 ft
Round as needed.
Answer:
4 - Double Parking
6- Perpendicular Parking
5- Hand over hand method
1 - Manual Transmission
3 - Push pull method
2 - Parking on a hill
Explanation:
Manual Transmission - requires a stick shift
Perpendicular Parking - type of parking in a parking lot.
Double Parking - Parking in the roadway
Hand-over-hand - Grab the far side of the wheel.
Push-pull Method - Slide your hand along the wheel.
Parking on a hill - Turn wheels toward curb.
