Determine the output pressure of a compressor operating with the following data: a. Actual power required to drive the compressor is 20 kW. b. Overall efficiency of the compressor is 75%. c. Compressor delivers four standard m3/min. d. Compressor inlet pressure is 100 kPa abs. Please use the equation in the picture to solve it.

= Knowledge Check: String in a Circle Please answer the following question(s): 1. Object of mass m tied at the end of a string of length R whirled around a circle. The tension in the string is T. How much work does T do on the object?

the what value of Q is profll Consider the following costs for a certain chemical product: Abin booge hl Fixed cost: $2.045 million/year. Variable costs: mor riaiugniraib orb lodal Material cost: 62 cents per gallon of product. Energy cost: 24 cents per gallon of product. Labor cost: 16 cents per gallon of product.

The left side of this equation tells how much energy Q the cylinder gives to the water while it cools. The right side of this equation tells how much energy Q the water and aluminum cup absorb from the cylinder to warm up. Because it is the same energy, they are equal. What is known in this equation? Mcyl 411.7 g, malum 46.5 g, malum+water = 175 g Can you find: mwater =? g Twater = Talum = 20°C (water and cup of room temperature) 90°C, T; = 35°C (hot cylinder and cool "cylinder+cup+water" temperatures) Tcyl kCal Calum = 0.22, Cwater 1 (specific heat of water and aluminum, measured in units kg-°C What are we looking for is Ccul - How we find it? Plug all the numbers into the equation (1), Ccul will be one unknown which you can calculate from the equation. Important, convert all the masses from grams to kilograms! After you find Ccyl, compare it to known value for the copper 0.093(our cylinder is made out of copper). |Ceyl -0.093| % : · 100% 0.093

Please help with this answer. I have also attached a list of all of the answers it is not. I just submitted this problem and it said the answer was incorrect so im looking for some additional help.
