THERMODYNAMICS A gas initially at P1 = 0.01 bar and v1 = 15 gal undergoes isothermal process and change state to a point where P2 = 0.06 bar and v2 = 4.5 gal. Compute the heat transferred. (use 1 bar = 14.5038 psi and 1 gal=0.004546m3)
An iron bar with an initial temperature of 10°C is heated such that its temperature increases at a rate of 4°C/min. The temperature, C, in degrees Celsius, at any time, t, in minutes, after heat is applied is given by the function c= 10 + 4t. The equation F= 1.8c + 32 is used to convert from C degrees Celsius to F degrees Fahrenheit. Determine the instantaneous rate of change of the temperature, in degrees Fahrenheit, of the bar with respect to time at 4 mins
10. A steam drum contains steam having an 86% quality. Assuming that the density of Liquid part is 989kg/m³ and that of the vapor part is 1.23kg/m³, Estimate the specific volume of the steam. (Note: 86% quality indicates the mass in vapor state) Derive with the formula below, show the cancellation, explain the step by step and DRAW a free body diagram/figure. refer with this: PE1 + KE1 + U1 + WF1 + Q1 + W1 = PE2 + KE2 + U2 + WF2 + Q2 + W2 + E losses.
Use the following conversions where necessary:1hp = 745.7W; ρwater = 1000 kg/m3; ρmercury = 13600 kg/m3; 1 atm = 101.325 kPa; Cp (water) = 4.18 kJ/kg °C; g = 9.81m/s2; For properties of air, use R = 0.287 kJ/kg K; Cv (air) = 0.718 kJ/kg K; Cp (air) =1.005 kJ/kg K The following table lists temperatures and specific volumes of water vapor at two pressures: Data encountered in solving problems often do not fall exactly on the grid of values provided by property tables, and linear interpolation between adjacent table entries becomes necessary. Using the data provided here, estimate i. the specific volume at T = 240 °C, p = 1.25 MPa, in m3/kg ii. the temperature at p = 1.5 MPa, v = 0.1555 m3/kg, in °C iii. the specific volume at T = 220 °C, p = 1.4 MPa, in m3/kg
A 227 kg bear* is 15 ft up a tree when it falls onto a trampoline deforming it 3 ft (where it touches the ground). Neglecting friction and mass of the trampoline (and assuming the trampoline is a simple spring), what is the spring constant of the trampoline? 1 m = 3.3 ft * the bear was OK a. 24,470.60 N/m b. 2,441.93 N/m c. 741.53 N/m d. 7,415.33 N/m
Data from a test on a NAPOCOR boiler, using pulverized coal, are as follows: Proximate Analysis of Coal Ultimate |Analysis of Coal W = 2.80 % C = 84.36 % N = 0.63 % VCM = 1.16 % H = 1.89 % S = 0.89 % FC = 88.21 % O = 4.40 % A = 7.83 % The coal rate is 11762 kg/hr and the excess air required is 35 %. Determine: a) the “as fired”coal analysis, and the “dry” coal analysis; and b) the actual air required per hour.
30lb of ice at 32°F is placed in 100lb of water at 100°F. The latent heat of ice may be taken as 144 BTU/lb, Cp of water=1BTU/lb°F, Cp of ice=0.5045 BTU/lb°F. a. 48°F b. 49°F c. 50°F d. 51°F

An ideal gas is confined to one side of a rigid, insulated container divided by a partition. The other side is initially evacuated. The following data are known for the initial state of gas: P1 = 5 bar, T1 = 500 K, and V1 =0.2 m3. When the partition is removed, the gas expands to fill the entire container, which has a total volume of 0.5 m3. Assuming that there is no change in the internal energy of the gas, determine the (a) pressure, in bar and the (b) product of mass, specific gas constant and T in the final state (in kPa-?3)
