5- The mechanical and indicated thermal efficiencies of 4-stroke four cylinder over square engine are (83% & 33%) respectively. The fuel calorific value of (42000) kJ/kg is consumed at a rate of (20 kg/hr.) when running at a fixed speed. The brake mean effective pressure developed is (6.4) bar. The combustion process was completed when the crank angle is 20° ATDC with piston speed ( 8.5 ) m/s and the volume is 80cm³, the ratio of connecting road

Solve the question given in the image attached Note question is taken from power plant course
A machine makes two components; call them types A and B. It takes 250 seconds to switch production between the component types. During that time, no production occurs. When in production, each unit of A or B requires 0.5 second to be completed. The two components, A and B, are combined in an assembly process to make a final product; call it C. The assembly step can combine the two components into 1 unit every 2 seconds, or 30 units per minute. Assume there is ample demand. Suppose the machine rotates between one batch of 1,000 units of A and 1,000 units of B. What is the average inventory of B components? answer:______units

True, False or Uncertain. Explain your answer. Own wage elasticity JELLlincrease if product demand elasticity n? is high. In short run, when there is an increase in wage rate, each firm will hire less labor and so the industry labor demand is simply the horizontal summation of firm's labor demand. а. b. Labor demand is represented by the marginal revenue produce schedule (MRP) when we have competitive product market while it will be represented by the value of marginal product schedule (VMP) when we have a product market monopolist. When elasticity of substitution, SLK, increase that means the L and K are less substitutable, and the isoquant will be L-shaped. Minimum wage imposed by the government is always bad for the economy because it increase unemployment and deadweight loss. с. d. e. 3.
