Air is to be heated by passing it over a bank of 3 m long tubes inside which steam is condensing at 100ºC. Air approaches the tube bank in the normal direction at 20ºC and 1 atm with a mean velocity of 5.2 m/s. The outer diameter of the tubes is 1.6 cm, and the tubes are arranged staggered with longitudinal and transverse pitches of SL = ST ...

Flow Across a Bank of Tubes: A bank of tubes is used to heat air at T∞ = 3 0 C. The tube bank consists of 2 1 rows of tubes, each with a diameter of D = 0. 0 5 m, L = 0. 5 0 m, and a surface temperature of Ts = 1 2 0 C. Air flows over the tubes at u∞ = 3 m / s. (a) Calculate the Reynolds number for the flow over ...

Air approaches the tube bank in the normal direction at 0°C and 1 atm with a mean velocity of 9 m/s. The tubes are arranged in-line with longitudinal and transverse Air is to be cooled in the evaporator section of a refrigerator by passing it over a bank of 0.8-cm-outer-diameter and 0.8-m-long tubes inside which the refrigerant is evaporating ...

In passing through the first coil bank, the air is heated to 75°F. The temperature of the water supplied to the spray chamber is adjusted to the wet-bulb Cold air at 20°F, 760 mm Hg pressure and 70% relative humidity is conditioned by being passed through a bank of heating coils, then through a water spray and finally through a second set of ...

At the beginning of 2024, Best Heating \& Air (BHA) has a balance of $25, 200 in accounts receivable. Because BHA is a privately owned company, the company has used only the direct write-off method to account for uncollectible accounts.

Air is to be heated by passing it over a bank of 3-m-long tubes inside which steam is condensing at 100°C. Air approaches the tube bank in the normal direction at 20°C and 1 atm with a mean velocity of 5.2 m/s. The outer diameter of the tubes is 1.6 cm, and the tubes are staggered with longitudinal and transverse pitches of SL = ST = 4 cm.

Air is heated in a tube bank. The 3 m long, 1.4 cm diameter tubes contain condensing steam at 100∘C. The air approaches the bank at 20∘C and 1 atm with a velocity of 5.2 m/s. The tubes have a staggered arrangement with a longitudinal pitch of 0.02 m and a transverse pitch of 0.075 m. There are 22 rows in the flow direction and 12 tubes in ...

1. air, which is flowing through a duct, passes through a bank of filters. the pressure drop across the filter bank is measured by a manometer filled with water. the manometer deflection is 17.2 cm. what is the pressure drop in kPa? In psi? 2.

Combustion air in a manufacturing facility is to be preheated before entering a furnace by hot water at 90°C flowing through the tubes of a tube bank located in a duct. Air enters the duct at 15°C and 1 atm with a mean velocity of 4.5 m/s, and it …

Question: Which of the following processes would promote radiation fog “burn off” (dissipation)? Group of answer choices warming surface air causing fog droplets to evaporate from the ground up absorption of solar radiation at the top of the fog bank precipitation cooling of the air along the periphery of the fog bank
