Explanation Write the Bernoulli’s equation between point 1 and the outlet. p 1 γ + V 1 2 2 g + h = p a t m γ + u x 2 2 g (I) Here, pressure is p , atmospheric pressure is p a t m , velocity is V , specific weight is γ , height of point 1 above the outlet is h , acceleration due to gravity is g and initial velocity of projection is u x . Conclusion: Refer Table 1.5, “Approximate Physical Properties of Some Common Liquids (BG Units)”; obtain the specific weight of water as 62.4 lb / ft 3 . Assume that the gun is at 5 ft above the ground, the distance between point 1 and outlet as 4 inches and the water coming out of the gun to be horizontal projection at 30 ft. Write the expressions of horizontal projection. R = u x t H = 1 2 g t 2 H = 1 2 g ( R u x ) 2 u x 2 = 1 2 H g R 2 (II) Here, distance of the gun from the ground is H and the distance of projection from the outlet is R . Substitute 5 ft for H , 32.2 ft / s 2 for g and 30 ft for R in Equation (II). u x 2 = 1 2 × 5 ft ( 32.2 ft / s 2 ) ( 30 ft ) 2 u x 2 = 2898 u x = 53.83 m / s At V 1 = 0 in Equation (I), P 1 γ + h = P a t m γ + u x 2 2 g (III) Substitute 62

1.21 A one-dimensional plane wall is exposed to convective and radiative conditions at x = 0. The ambient and sur- rounding temperatures are T = 20°C and Tur = 40°C, respectively. The convection heat transfer coefficient is h=20 W/m² K, and the absorptivity of the exposed sur- face is α=0.78. Determine the convective and radiative heat fluxes to the wall at x = 0 if the wall surface tem- perature is T, = 24°C. Assume the exposed wall surface is gray, and the surroundings are large.

1.12 You've experienced convection cooling if you've ever extended your hand out the window of a moving vehi- cle or into a flowing water stream. With the surface of your hand at a temperature of 30°C, determine the con- vection heat flux for (a) a vehicle speed of 40 km/h in air at -8°C with a convection coefficient of 40 W/m² K and (b) a velocity of 0.2 m/s in a water stream at 10°C with a convection coefficient of 900 W/m²K. Which condition would feel colder? Contrast these results with a heat flux of approximately 30 W/m² under normal room conditions.
