Per Bartleby honor code only 3 subparts of a question can be answered per submission. I have submitted 10, 11, 12, and 13 previously. Please answer 14, 15, 16

I need parts 8, 9, and 10 answered. Number 1 is an example of how it should be answered. NOTE: Read the instructions, no where does it say any drawing is required. It is really frustrating when I wait all this time for an answer to a question and some tutor does even read the instructions and just declines it...its ridicilous.

Mech. Engg. Dept. 4th year 2022-2023 Solar Energy Spring course MEC364 Dr. Mahmoud U. Jasim Review/Recap Sheet Q1- Answer with true or false and rewrite the false statements completely in correct form, otherwise no mark will be put on the false statements. 1 2 To represent a location on earth surface you need to define its altitude and longitude angles. 3 Solar zenith and solar incidence angles have the same value for horizontal surface. At sunset time the value of solar altitude angle is maximum. 4 The angle which represents the inclination of a given surface is the zenith angle 5 6 7 8 When the absolute value of sun-wall azimuth angle exceeds 90' this means that the sun rays are reaching the receiving plane. The solar irradiance and the solar irradiation have the same physical meaning. In the case of clear sky weather, the beam solar irradiation on a horizontal surface is less than the diffused irradiation. The total solar radiation received by a tilted surface is the same as that…

QUESTION 1Kindly answer correctly. Please show the necessary steps. Thanks in advance.

LESSON: ZEROTH LAW OF THERMODYNAMICS AND TEMPERATURE MEASUREMENTMODIFIED TRUE or FALSE Directions: Write TRUE if the statement is correct, otherwise, change the underlined word/s or values to make the statement correct. Write your answer on the space provided before each item number. Statement: The Philippine one-peso coin has a diameter of 23.0 mm at 25 room temperature. Assume that the coin is made up of steel.14. The increase in coin’s diameter when placed in boiling water is 0.0207 mm.15. The final length of coin when placed in boiling water is 23.207 mm.16. If the coin is heated at 42 degrees Celsius, then the increase in diameter is 0.0207 mm.17. If the initial temperature is doubled, then the increase in coin’s diameter when placed in boiling water is 0.0414 mm.

Good day. I am trying to review for examinations and require assistance for these questions... Thermal Energy: Find BTE and ITE using the BHP AND IHP that you have calculated for number 4 and number 5. Assume you have a gasoline that burns for 7 gal/hr with a heat value of 18000 BTU    Mechanical Efficiency: Find the Mechanical Efficiency of an engine with a 6-cylinder engine which a bore of 6.28 inches and a stroke of 3.5 inches with an IMEP of 400 psi and BMEP of 300 psi at 1825 rpm.    Volumetric Efficiency: What is the volumetric efficiency of a four-cylinder aircraft engine which has a bore of 4 inches and a length of stroke of 6 inches and 30 cu in. volume of charge     **Would appreciate a detailed explanation. Thank you so much.

I need answers to questions 7, 8, and 9 pertaining to the print provided. Note: A tutor keeps putting 1 question into 3 parts and wasted so many of my questions. Never had a issue before until now, please allow a different tutor to answer because I was told I am allowed 3 of these questions.

ADVANCED CHEMISTRY! RATE WILL BE GIVEN! PLEASE WRITE THE COMPLETE SOLUTIONS A Steam at 400 deg C an 8,200 kilo Pascals enters a turbine and leaves at 10 kPa. What is the entropy of the leaving steam if the efficiency of the turbine is 0.76. Round the answers in to 2 decimal places.

Questions (Wind Energy) Q1: The average wind velocity in a particular area is found to be 5.5m/s. It is proposed to install a wind driven turbine with a blađe radius of 1.8m. The proposed design has an interference factor of 0.21 and an axial force coefficient of 0.89, and a torque coefficient of 0.8. Determine: a) The expected power output of the turbine. b) Thrust on the turbine. c) Torque on the turbine. d) Rotational speed. Q2: Wind speed measurements at a particular location have been obtained with a view to the possible installation of a wind turbine. The anemometer was located 12.5m above the ground level. The average wind speed recorded during the testing was 9.2m/s. Estimate the variation in wind speed across the 40 m diameter of the proposed turbine if the hub is installed 30m above the ground.
