Answer:
The difference in weight and size?
Explanation:
It explains itself :P
Answer:
momentum
Explanation:
Mass - Mass is a measurement of how much matter is in an object. It is usually measured in kilograms. Momentum is equal to the mass times the velocity of an object. Momentum is a measurement of mass in motion
Answer: 383.22K
Explanation:
L = 3m, w = 1.5m
Area A = 3 x 1.5 = 4.5m2
Q' = 750W/m2 (heat from sun) ,
& = 0.87
Q = &Q' = 0. 87x750 = 652.5W/m2
E = QA = 652.5 x 4.5 = 2936.25W
T(sur) = 300K, T(panel) = ?
Using E = §€A(T^4(panel) - T^4(sur))
§ = Stefan constant = 5.7x10^-8
€ = emmisivity = 0.85
2936.25 = 5.7x10^-8 x 0.85 x 4.5 x (T^4(panel) - 300^4)
T(panel) = 383.22K

Answer
diameter of parking lot = 18 in
flowrate = 10 ft³/s
pressure drop = 100 ft
using general equation



taking f = 0.0185
at Z₁ = Z₂

ΔP = 0.266 psi
b) when flow is uphill z₂-z₁ = 2


c) When flow is downhill z₂-z₁ = -2
