The constant-pressure specific heat of air at 25°C is 1.005 kJ/kg·°C. Express this value in kJ/kg·K, J/g·°C, kcal / kg·°C, and Btu/lbm·°F. Round the final answers to three decimal place

For beam design, the cross section dimensions of the beam are determined: A. Based on allowable normal stress, but the allowable shear stress should always be checked to be sure it is not exceeded. B.

The properties of the air in the inlet section with A1 = 0.25ab m2 in a converging-diverging channel are given as U1 = 25a, b m/s, T1 = 3ab K, P1 = 13a, b kPa (absolute).

Consider a large plane wall of thickness L = 0.4 m, thermal conductivity k = 2.3 W/m·K, and surface area A = 30 m2.

A local reaction is when a chemical enters the bloodstream?

The rules for ordinary arithmetic involving addition, subtraction, and multiplication carry over into modular arithmetic. Tru

An air-conditioning system is used to maintain a house at 70°F when the temperature outside is 100°F. The house is gaining heat through the walls and the windows at a rate of 800 Btu/min, and the heat generation rate within the house from people,

The electricity we use is static or current electricity?
