The terrace roof of a building at sea level is planned to have a rectangular floor area with dimensions of 10 m and 20 m. The prevailing wind speed in winter is u∞=25 km/h, and air temperature is assumed to be T∞=0°C. Considering that the outer surface temperature of the building is To=10°C, how should the building be positioned with respect to the prevailing wind direction to minimize the heat loss from the roof?

A proposed water tank on the sixth floor (roof top) of the UTPA administration building would be used to supply pressurized water for the campus. A pump fills the tank at a rate of 15.6 kg/s. What size motor (hp) is needed to operate the pump given the data below? The motor size (hp) must be 20% greater than the required pump work. Note: Give the motor size as a positive value. The pump includes the riser pipe to the...

(a) Stations A and B are at the same sea surface elevation level and have a bottom depth of 2000 m. Both stations have seawater with a uniform density with respect to depth; however the seawater density at A and B are different (sA = 24.7 kg/m3 ; sB = 25.4 kg/m3 ). [A = 40o 45' N, 25o 45' W; B = 41o 5' N, 24o 45' W] (b) Does this current vary with respect to depth ? If...

Problem 3 A column supports a roof and a second floor. The loads that act on the column are shown below. Using the ASCE 7 load combinations determine the factored design load in the column just above the second floor and the factored design load in the column just above the foundation. Show all load combination calculations and identify the controlling load combination and resulting load values at each design location. ( “ - “ load : indicates it is...

A ball is thrown straight up from the edge of the roof of a building. A second ball is dropped from the roof a time of 1.20 s later. You may ignore air resistance. A) If the height of the building is 20.7 m , what must the initial speed be of the first ball if both are to hit the ground at the same time? B) Consider the same situation, but now let the initial speed v0 of the...
